a. did not pay enough
b. paid the correct amount
c. paid $2.60 too much

Answer 1

the price of all gallons 12*(2.89)=$34.68
a) the price of the granola bars 2*(1.59)=$3.18
b) 1 apple=$0.89
c) 2 bottles of vitamin 2*(1.39)=$2.78

a)+b)+c)=6.85$, the 7.5% of this amount is $0.51

so finally, Leon should have paid $6.85+ $0.51+ $34.68 =$42.04

but he paid $44.64, so the true answer is C) he paid $2.60 too much ($44.64 - $42.04 =$2.60)

The number of granola bars = $1.59

The number of granola bars bought = 2

The amount Leon paid = $44.64

The total amount spent is given as follows;

12 × 2.89 + 2 × 1.59 + 0.89 + 2 × 1.39 × (1 + 0.075) = 44.64475 ≈ 44.64
