Directions:Write inequalities for the numbers 2 - 4 below. Do not solve them!

Problems:
2.Your quiz grades are 19, 17, 20, and 15. What is the lowest grade you can receive on the next quiz and maintain at least an 18 average?

3.Stacey and Luis volunteer at the local hospital. Stacey worked 4 more hours than Luis, and together they worked more than 28 hours. What is the least number of hours each worked?

4.Mrs. Culpepper has promised her two sons that they may go to a concert if together they save more than $45. The older son agrees to save twice as much as the younger one. How much must each save?

this is what i got for #2:
(19 + 17 + 20 + 15 + X)/5 18




(19 + 17 + 20 + 15 + X)/5 ≥ 18

Older son saves X. Younger son saves X/2
X + X/2 >or= 45
3X/2 >or= 45
X/2 >or= 15
Take it from there
