Let x be the score of the 3rd quiz,, then the average score will be:
(83+91+x)/3, which = (174+x)/3. but this average should be greater or equal to 85 and smaller or equal to 90:

85 ≤ (174+x)/3 ≤ 90
1st multiply all terms with 3 → 255 ≤(174+x) ≤ 270
2nd subtract 173 from all terms → 255-174 ≤174-174+x ≤270-174
81 ≤ x ≤ 96

tigry1 [53]

The difference between the price per pound for the three pound bag of oranges and the price per pound for the 5 lb bag of oranges is $0.15

Given

Price of 3lb bag = $3.60

Price of 5lb bag = $5.25

We have to calculate the per pound price for each bag to compare the per pound price for both

Price of one pound in 3lb bag-

\frac{3.60}{3}=$1.20

Price of one pound in 5lb bag-

\frac{5.25}{5} = 1.05

Difference between the prices-

1.20-1.05= 0.15

The difference between the price per pound for the three pound bag of oranges and the price per pound for the 5 lb bag of oranges is $0.15
