You are saving money to buy a new bicycle that costs $155.75. You have $30 and plan to save $5 each week. Your aunt decided to give you an additional $10 each week.
How many weeks will you have to save until you have enough money to buy the bicycle?
1. $155.75 - $30 = $125.75
2. $125.75 / $15 = 8.4
So, saving up money will take about 8.4 weeks.
To calculate the number of weeks needed to save enough money for the bicycle, we need to consider the amount of money you have, the amount you plan to save per week, and the amount your aunt is giving you per week.
You currently have $30.
You plan to save $5 per week.
Your aunt is giving you an additional $10 per week.
The total amount needed to buy the bicycle is $155.75.
To calculate the number of weeks needed, we can subtract the money you currently have from the total cost of the bicycle and divide it by the combined weekly savings:
$155.75 - $30 = $125.75
$5 + $10 = $15
$125.75 / $15 = 8.383, approximately
Therefore, you will need to save for approximately 8.4 weeks until you have enough money to buy the bicycle.
To calculate the number of weeks it will take to save enough money to buy the bicycle, we need to determine how much money you are saving each week.
You are saving $5 per week, and your aunt is giving you an additional $10 per week, which gives a total of $5 + $10 = $15 per week.
Now let's calculate how much money you need to reach your goal:
Cost of the bicycle = $155.75
You currently have $30. Therefore, you need to save an additional amount to reach your goal:
Amount needed = Cost of the bicycle - Amount already saved
= $155.75 - $30
= $125.75
Now, let's calculate the number of weeks it will take to save enough money:
Number of weeks = Amount needed / Amount saved per week
= $125.75 / $15
≈ 8.38 weeks
Since you cannot have a fraction of a week, we round up the number of weeks to the nearest whole number.
Therefore, you will have to save for approximately 9 weeks until you have enough money to buy the bicycle.
