Answer:

The original price was $28.

Step-by-step explanation:

Let the original price be = x

There was 40% off on x.

So, sales price was = x-0.40x=0.60x

Tt was then put on clearance an additional 25% off the sale price.

Means the price now becomes: 0.60x-0.25(0.60x)=0.45x

With the help of coupon, she got $5 off and paid no more than $7.60, so the equation becomes:

0.45x-5\leq 7.60

=> 0.45x \leq 7.60+5

=> 0.45x \leq 12.60

=> x\leq 28

Hence, the original price of the sweater was $28.

Answer:

The least amount spent is £12.92

Step-by-step explanation:

Given

Number of Carton = 38

A carton = 45 pence

4 carton = £1.56

To spend the least amount of money, be needs to go for the least expensive option.

There are 100 pence in £1

So, there are x pence in £1.36

x * 1 =1.36 * 100

x = 136 pence for 4 carton.

To get the price of 1 carton, divide x by 4

x/4 = 136p/4

x/4 = 34 pence.

This means that he can get a carton of juice at the rate of 34p and at the rate of 45p.

The smallest of this is 34p.

Hence total amount spent =

34 * 38

amount = 1292p --- convert to £

Amount = 1292/100

Amount = £12.92

Hence, the least amount spent is £12.92
