Answer
The unit price of the first offering is 0.45 dollars.
The unit price for the second offering is 0.40 dollars.
Work Step by Step
Let x represent the price of one apple.
a) The store offers 3 apples for 1.35, so we set up this proportion:
$\frac{3}{1}$ = $\frac{1.35}{x}$
To solve this equation, we equate the cross products.
3 $\times$ x = 1 $\times$ 1.35
3x = 1.35
Divide both sides by 3.
x = 0.45
The unit price of the first offering is 0.45 dollars.
b) The store offers 5 apples for 2.00, so we set up this proportion.
$\frac{5}{1}$ = $\frac{2.00}{x}$
To solve this equation, we equate the cross products.
5 $\times$ x = 1 $\times$ 2.00
5x = 2.00
Divide both sides by 5.
x = 0.4
The unit price for the second offering is 0.40 dollars.
