At Frugal Foods a loaf of bread cost about $1 in 1980. In 2013, the loaf of bread cost $2.50
1. A ratio is a comparison of two amounts by division. What is the ratio of the
cost of a loaf of bread in 2013 to the cost in 1980?
2. Assuming the price of clothing increased at the same rate, if the cost of jeans at Cobb's Corner was $15 in 1980, what would be the cost of the jeans be in 2013? Explain. I really don't get this problem, I searched everywhere, no one can explain it to me.
1. 2.5:1 or 5:2
2.using the ratio from part a 2.5:1 ....As it cost 15 in 1980 now you get a ratio x:15
2013 1980
2.5 : 1
x : 15
To get 15 we must times both sides by 15... so 15 x 2.5 is $37.5.
1. Ah, the price of bread! Always rising like yeast on a warm day. Anyway, to find the ratio of the cost of a loaf of bread in 2013 to the cost in 1980, we simply divide the cost in 2013 by the cost in 1980. So, $2.50 ÷ $1 equals... *drumroll*... $2.50. Ta-da! The ratio is 2.50:1.
2. Now, let's put on our stylish thinking caps and tackle the jeans problem. If the cost of jeans at Cobb's Corner was $15 in 1980 and assuming the price increased at the same rate as the loaf of bread, we can use the ratio we calculated earlier (2.50:1) to solve the mystery.
We start by multiplying the cost of jeans in 1980 ($15) by the ratio (2.50) to find the cost of jeans in 2013. So, $15 × 2.50 equals... $37.50! Voila! The cost of jeans in 2013 at Cobb's Corner would be $37.50. There you have it, an outfit that costs more than just your legs!
1. To find the ratio of the cost of a loaf of bread in 2013 to the cost in 1980, you divide the cost in 2013 by the cost in 1980:
Ratio = Cost in 2013 / Cost in 1980
In this case, the cost in 2013 is $2.50 and the cost in 1980 is $1.
Ratio = $2.50 / $1 = 2.5
Therefore, the ratio of the cost of a loaf of bread in 2013 to the cost in 1980 is 2.5:1.
2. To find the cost of jeans in 2013 at Cobb's Corner, assuming the price increased at the same rate as the loaf of bread, you can use the ratio calculated in the previous step.
Cost of jeans in 2013 = Cost in 1980 * Ratio
In this case, the cost of jeans in 1980 is $15, and the ratio is 2.5:1.
Cost of jeans in 2013 = $15 * 2.5 = $37.50
Therefore, the cost of jeans in 2013 at Cobb's Corner would be $37.50.
1. To find the ratio of the cost of a loaf of bread in 2013 to the cost in 1980, we need to divide the cost in 2013 by the cost in 1980. So the ratio can be calculated as follows:
Ratio = 2013 cost / 1980 cost
In this case, the 2013 cost is $2.50 and the 1980 cost is $1. Plugging these values into the formula, we get:
Ratio = $2.50 / $1
Simplifying the division, we find that the ratio is 2.5.
Therefore, the ratio of the cost of a loaf of bread in 2013 to the cost in 1980 is 2.5:1.
2. To determine the cost of jeans in 2013 based on the assumption that the price increased at the same rate, we can use the ratio we found in question 1.
We know that the cost of jeans at Cobb's Corner was $15 in 1980. By scaling up this price using the ratio, we can calculate the cost in 2013.
Cost in 2013 = 1980 cost * ratio
Plugging in the values, we get:
Cost in 2013 = $15 * 2.5
Simplifying the multiplication, we find that the cost of jeans in 2013 would be $37.50.
Therefore, if the price of clothing increased at the same rate as the cost of bread, the cost of jeans at Cobb's Corner in 2013 would be $37.50.
