Question

Number 35 Plz someone help me in this problem ❤️

Answer 1

Greetings!

This can be solved by creating an algebraic equation:
$8.75(30)+11x=400$

Solve for x.
$262.5+11x=400$
Add -262.5 to both sides.
$(262.5+11x)+(-262.5)=(400)+(-262.5)$
$11x=137.5$
Divide both sides by 11.
$(11x)/11=(137.5)/11$
$x=12.5$

You must work 12.5 hours as landscaper to earn $400 a month.

Hope this helps.
