70x + 90y = 2220

Step-by-step 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}
