3. gabriela is washing cars. she charges $15 for a car wash. she paid $145 for advertising, and uses $3 worth of cleaning products on each car she washes. when will gabriela begin to make a profit?

a) write an inequality to model the problem.
b) solve the inequality. show your work.
c) answer the question from the problem.

she will make a profit after the 12th car.

explanation-    x(15−3)−145>0 to find when she starts to make a profit:

So:

12x−145>0

12x>145

x>14512=12.08≈12  

if x=13:

13⋅12−145=$11

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

a; x = 0.5
