Answer:

[tex]Total\ Savings = 63[/tex]

[tex]Average\ Savings = 21[/tex]

Step-by-step explanation:

Given

[tex]Amount = 210[/tex]

[tex]Savings = 30\%[/tex]

Solving (a) Total Savings Mode

[tex]Total\ Savings = Savings * Amount[/tex]

[tex]Total\ Savings = 30\% * 210[/tex]

[tex]Total\ Savings = 63[/tex]

Solving (b): Savings per person

Since, there are 3 individuals involved;

[tex]Average\ Savings = \frac{Total\ Savings}{3}[/tex]

[tex]Average\ Savings = \frac{63}{3}[/tex]

[tex]Average\ Savings = 21[/tex]

Answer:

a = €90

b = £30

Step-by-step 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
