Question

Victoria has soccer three times a week, swimming four times a week, and piano twice a week.

She spends a total of 435 minutes each week doing these three activities a week. Write an
equation that represents this situation.

Answer 1

3x + 4y + 2z = 435

Explanation:

let x represent soccer

hence playing soccer three times = 3 × x = 3x

let y represent swimming

hence swimming four times = 4 × y = 4y

let z represent piano

hence playing piano twice = 2 × z = 2z

Victoria spends a total of 435mins doing these three activities every week,

3x + 4y + 2z = 435
