Step-by-step explanation:

Nomenclature

C: Total cost of apples ( dollars)

n: number of apples (units)

r : ratio of the amount in dollars to the number of apples (dollars/number of apples)

Formula : r = C/n

Problem deveopment

a. ratio of the amount in dollars to the number of apples

r = C/n= 1.25 dollars /1 apple = 1.25 dollars/apple

b. Apples that Akia can buy

r = C/n

n=C/r

n= 8 apples

Akia can buy 8 apples

c. Apples that Christian can buy

n=C/r

n=6/1.25

n= 4.8

The number must be an integer, then, Christian can buy 4 apples
