On Sunday, the high temperature was 71° F, but on Monday it was 5° F lower. What was the percent change?

The percent change is -7%.

Step-by-step explanation:

In order to find the answer, you can use the following formula:

Percent change=(New value-Old value/Old value)*100

New value=71-5=66

Old value=71

Now, you can replace the values on the formula:

Percent change=(66-71/71)*100

Percent change=(-5/71)*100

Percent change=-0.07*100

Percent change=-7%

According to this, the answer is that the percent change is -7%.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
