FOOD: each variety of apples cost $1.20/lb at a grocery store. you buy 4lbs of cortland apples and some gala apples for eating. the total cost is $7.20. how many lbs of gala apples did you buy?
i think i got the answer but not sure how to write it in equation.
Total $7.20 - 5.16 = $2.04 difference
4lb cortlad apple @1.29 = 5.16
? gala apples @1.29 = 2.04/1.29 =
1.581395349 lbs of gala bought
im not sure how to write this as equation
1.29 (x + 4) = $7.20
so 4lb at 1.20 = 4.80
2lb at 1.20 = 2.40
ttl 7.20
gala apple bought 2lb
(1.2 * 4) +x = 7.20
4.80 + x = 7.20
4.80 -4.80 + x = 7.20 - 4.80
x = 2.40
thanks for your help and sorry again
(1.2 * 4) + x = 7.2
Solve for x
Each pound of apples costs $1.20.
" each variety of apples cost $1.20/lb"
Im sorry i kept writing $1.29 and yes
1.20 sorry thanks
To write the equation for this problem, let's assign a variable to represent the number of pounds of gala apples you bought. Let's call it "x".
Since each variety of apples costs $1.20 per pound, the cost of the gala apples would be $1.20 multiplied by the number of pounds of gala apples you bought, which is represented by 1.20x.
The total cost of the 4 pounds of cortland apples and the gala apples is given as $7.20. So, the equation becomes:
$1.20 (x + 4) = $7.20
Here, we multiply the cost per pound ($1.20) by the sum of the number of pounds of gala apples (x) and the 4 pounds of cortland apples (4), and set it equal to the total cost ($7.20).
Simplifying this equation will lead you to the correct answer.
why (1.2 *4)
should it be: (1.29*4) +x = 7.20?
