<u><em> </em></u>

<u><em>Given: </em></u>

<u><em>w(h) represents how many hours per week </em></u>

Manny bought 12 pounds of vegetables
finlep [7]

Answer:

Manny bought 3 pounds that were not on sale

Step-by-step explanation:

If 75 % were on sale,  (100% -75% = 25%)  then 25% were not on sale  (The total has to be 100%)

Manny bought 12 pounds of vegetables

To determine how many pounds were not on sale, we take the amount of vegetables purchased and multiply by the percent that were not on sale.

12 * 25%

Change this to decimal form

12 *.25

3

Manny bought 3 pounds that were not on sale

The answer would be 53. This can be found by add 127 twice (xy and uz) and subtracting it from 360. This would give you 106 and you would divide it by 2 for the 2 angles left and get the answer.
