Answer:
15x+100(3) ≥ $1500
x ≥ 80 pages
Step-by-step explanation:
Let x represent the number of pages.
Manuel receives $15 per page = 15x
Plus $100 per month. Manuel would like to work for 3 months = 15x+100(3)
He wants to make at least $1500 during the summer
Thus the inequality we get is:
15x+100(3) ≥ $1500
Now solve the equation to find minimum number of pages:
15x+300 ≥ $1500
Combine the like terms:
15x ≥ 1500-300
15x ≥ $1200
Divide both sides by 15
15x ≥ $1200/15
x ≥ 80 pages
You plug in the numbers where the variable is so 4(1)-12
4(3)-12
4(5)-12
4(7)-12
if there is a number next to () then you multiply. so 4×1=4-12=8
