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

(1.2 * 4) + x = 7.2

Solve for x

why (1.2 *4)

should it be: (1.29*4) +x = 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
