Answer:
a. 80%
b. £34
c. £340
Step-by-step explanation:
a. We are given that Mrs Trent spent 20% of her weekly wage on food. This means she would have 80% of her weekly wage left with her.
b. 10% of Mrs Trent weekly wage:
If 20% = £68
10% = (10*68)/20 = £34
c. Let x represent weekly wage of Mrs Trent
Given that she spends £68 of x (weekly wage) on food, which is 20% of x.
This means that, 20% of x = £68
Let's find her weekly wage, x:
Divide both sides by 0.2
x = 340
Her weekly wage is £340.
