Answer:
Sharon bought a necklace with 90% blue beads.
Step-by-step explanation:
We are given that Sharon's necklace has 80 beads. We are also given that of those 80 beads, 72 of them are blue.
Therefore, we can set up a ratio of blue beads to total beads in order to find out the relationship.
Then, using the fraction we receive as a result, we can convert this to a decimal.
After we complete this calculation, we can multiply our decimal by 100 in order to obtain the relationship in percentage form.
Of the 80 beads, 90% were blue beads.

Solving (a) Total Savings Mode
Solving (b): Savings per person
Since, there are 3 individuals involved;
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
