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.
Avery is 1 under par or -1.
What we need to do to solve this is turn each of her scores into a number. If it says under par, we make it a negative. If it says over par, we make it a positive. If it is even par, it is a 0. The following should be her statement.
0 + 1 - 2 + 0 - 1 + 1 + 3 - 2 - 1
Which is equal to -1.
Answer:
.05(80) + .15(120)=
4 + 18 = 22
So, the total pick ups is 22.
