So i just started modeling and two step inequalities and my question is 62°f and it drops 2 degrees every hour .how many hours was it before the temperature was below 40°

It was 11 hours because if the temperature drops 2 degrees after every hour, after 11 hours, the temperature would have dropped 22 degrees and 62 - 22 = 40.

11 hours

Equation:

62 - 2x = T

62 - 2(11) = 40

the answer is d. 75%

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
