Question

PLEASE HELP I DONT KNOW WHAT TO DO

You buy 15 apples and a $2.75 block of cheese. The bill is $6.20. WRITE and SOLVE and EQUATION to find "a" the cost of each apple

Answer 1

a=0.23

Explanation:

1. first we need to make an equation we know 15apples plus a block of cheese that costs $2.75 adds up to $6.20 so we would write this as

15a+2.75=6.20

(the reason we write 15 apples as 15a is because we don't know how much each apple cost but we know there is 15 of them)

2. the aim of the question is to figure out how much each apple cost so we would get a on its own we would do this by -2.75 from each side and divide by 15 to get the coast of each apple

15a=3.45

(from this we know 15 apples cost 3.45 but we want to know what each apple coast so we divide by 15 on each side)

a=0.23

so each apple coast 0.23
