Mrs trent spends £68 on her weekly food shop.
salantis [7]

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:

\frac{20}{100} * x = 68

0.2x = 68

Divide both sides by 0.2

x = 340

Her weekly wage is £340.

Lisa [10]

Answer:

<em>550ft²</em>

Step-by-step explanation:

<em>Since we are not given the dimension of the rectangular prism. Let us assume;</em>

Length of the rectangular base L = 10ft

Width of the rectangular base W = 15ft

height of the prism H = 5ft

Total surface area of the prism = 2(LW + WH + LH)

Substitute the given values

Total surface area of the prism = 2{10*15 + 15*5 + 10*5}

Total surface area of the prism = 2(150+75+50)

Total surface area of the prism = 2(275)

<em>Total surface area of the prism = 550ft²</em>
