Question

As a promotional offer, a new gym is offering a 30% discount to those who sign up in the first month. Patty and her 2 siblings take advantage of the offer and sign up for a total amount of €210. What were the total savings mode?

Work out the average savings per person

Answer 1

a = €90

b = £30

Explanation:

They had a discount of 30% means that they paid 70%.

100% (total percentage ) - 30%( discounted for them) = 70% ( meaning they paid for 70% instead of 100%).

To find the total saving made, we need to know the total cost without the promo and substract from the 70% payment made.

70% payment made = €210.

1% = [210/70 = €3].

if 1% = €3, then 100% willl be €300.

100% the gym offers = €300.

Total saving made = total cost the gym offers - the 70% payment made.

€300 - €210 = €90.

If you want to be sure. 30% of €300 = 90.

meaning that they had a discount of €90.

If they paid €210 + €90 = €300.

b) The avearge saving per person?

Remember the question said Patty and 2 siblings, suggest they are 3 people in the picture.

If the 3 saved €90,

averge of one person:

90/3 = €30

Answer 2

`Total\ Savings = 63`

`Average\ Savings = 21`

Explanation:

Given

`Amount = 210`

`Savings = 30\%`

Solving (a) Total Savings Mode

`Total\ Savings = Savings * Amount`

`Total\ Savings = 30\% * 210`

`Total\ Savings = 63`

Solving (b): Savings per person

Since, there are 3 individuals involved;

`Average\ Savings = (Total\ Savings)/(3)`

`Average\ Savings = (63)/(3)`

`Average\ Savings = 21`
