Question

A shoe store sells two different styles of shoes. Style A sells for $90 and Style B sells for $70.You went into the store and spent a total of $2220 on shoes. Let x represent style B and let yrepresent style A. Write a linear equation in standard form that shows the relationship above.(

Answer 1

70x + 90y = 2220

Explanation:

The cost for style A = $90

The cost of style B = $70

let x = number of style B shoes

let y = number of style A shoes

Total amount spent on shoes = $2220

The relationship between the amount and style of shoe bought:

The cost for style A (number of style A) + The cost of style B (number of style B) = Total amount spent on shoes

90(y) + 70(x) = 2220

90y + 70x = 2220

Linear equation in standard form is given as:

$Ax\text{ + By = C}$

Rearranging the linear equation we got in standard form becomes:

$\text{70x + 90y = 2220}$
