Brian spends
1
4
of his wages on rent and
1
8
on food. If he makes £168 per week, how much money does he have left?

Brian have £105 left.

Step-by-step explanation:

Given,

Amount earned by Brian per week = £168

Fraction spent on rent = 1/8

Amount spent on rent = 1/8 x 168

Amount spent on rent = £42

Fraction spent on food = 1/8

Amount spent on food = 1/8 x 168

Amount spent on food = £21

Amount left = Amount earned - amount spent on rent - amount spent on food

Amount left = 168 - 42 - 21

Amount left = £105

Brian have £105 left.

I hope this helps you

x= 35

Step-by-step explanation:

3x-1 +31+45=180

3x+75=180

Subtract 75 on both sides

3x/3 = 105/3

x=35

Hope this helps.
