Question

Alex, bella, cara share £90; work how much each of them have if:

alex has £x
bella has 3 times as much as alex
cara has £10 less than alex​

Answer 1

Explanation:

given,

alex = x

bella = 3x

cara = x - 10

and also given,

`x + 3x + (x - 10) = 90 \\ x + 3x + x - 10 = 90 \\ 5x - 10 = 90 \\ 5x = 90 + 10 \\ 5x = 100 \\ x = 100 / 5 \\ = 20`

Given x = £20,

Alex = £x = £20

Bella = £3x = £3x20 = £60

Cara = £(x-10) =£(20-10) =£10
