Answer: you save $24.7 by buying the headphone at store A

Step-by-step explanation:

The price of a pair of headphones

at store A is 98.80. The price of a pair of headphones at store A is 4/5 the price at store B. Let x represent the price of a pair of headphones at store B. It means that

4/5 * x = 98.80

4x/5 = 98.80

Multiplying the left hand side of the equation and the right hand side of the equation by 5, it becomes

4x = 98.80 * 5 = 494

x = 494/4 = 123.5

The amount saved by buying the headphone at store A is 123.5 - 98.80 = $24.7
