Sagot :

$5.25 (option A)

Explanation:

Cost of a pound of flour = $1.12

Cost of 4.5 pounds = 4.5 × $1.12

Cost of 4.5 pounds= $5.04

Cost of a pound of baking soda = $0.82

Cost of 0.25 pound of baking soda = 0.25 × $0.82

Cost of 0.25 = $0.205

The total cost of 4.5 pounds of flour and 0.25 pounds of baking soda = Cost of 4.5 pounds + Cost of 0.25 pound of baking soda

= $5.04 + $0.205

The total cost of 4.5 pounds of flour and 0.25 pounds of baking soda = $5.245
