Regarding <span>x-2/5 = 1/5
We are to solve for x. To do this, let's remove the fractions by mult. all 3 terms by 5. Then 5x - 2 = 1, or 5x = 3.
Dividing both sides by x, we get x = 3/5 (answer). Check this by subst. 3/5 into the original equation.</span>
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
