Answer:Price of laptop A = $1220

Step-by-step explanation:

Sum of the price: A + B = 2185

Sum of the price: A + C = 2571

B : C = 5 : 7

B = 5/7 × C

So, replace the B:

A + 5/7 C = 2185

A + C = 2571

Eliminate by subtracting the first from the second: 2/7 C = 386

C = 1351

So, A = 2571 - 1351 = 1220
