Jawaban: #1:

Jawaban:

Assume

tennis racket = x

tennis ball = y

Given:

Anna bought:

2x + 6y = $182

Bella bought:

4x + 6y = $340

therefore each item price can be calculated.

2x + 6y = 182

4x + 6y = 340

y can be eliminated by subtracting first function with second function and therefore:

-2x = -158

x = 79

the price of a tennis racket is $79 so total amount of Clara's shopping is

6x = 6 x 79 = $474
