Answer:

Question 1

Was the price per ounce reduced by the same percent as the size of the cup? No it's not the same

Question 2

If not, find the price difference per ounce in terms of a percent.

13.8%

Explanation:

The first yoghurt cup size = 9 oz

The second and recent yoghurt cup size = 7 oz

The difference in ounces = 9 oz - 7 oz

= 2 oz

Converting this difference to percentage

= 2 oz/ 9 oz × 100%

= 22.222222222%

The percent reduction in cup size is approximately

22.2%.

The first retail price per ounce = 87 cents

The second and recent retail price per ounce =75 cents

The difference in prices = 87 cents - 75 cents

= 12 cents

Converting this difference to percentage

= 12 cents / 87 cents × 100%

= 13.793103448%

The percent reduction in yoghurt price per ounce is approximately

13.8%.

Question 1

Was the price per ounce reduced by the same percent as the size of the cup?

From the above calculation,

Percent reduction in price per ounce =

13.8%

Percent reduction in the size of the cup = 22.2%

13.8% ≠ 22.2%

Therefore, it is not the same

Question 2

If not, find the price difference per ounce in terms of a percent.

Therefore, the price difference per ounce in terms of percent is

13.793103448%.

Approximately ≈ 13.8%
