Write a story problem that includes both integers −8 and 12.

Sea level is 0 meters. A cliff by the ocean is 12 meters above sea level. Around that area, the seafloor is 8 meters below sea level. How many meters  is the top of the cliff to the seafloor?

How to solve:

8 below zero is -8

The expression 12 - (-8) is the same as the expression 12 + 8

12 + 8 = 20

20 meters

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
