Question

Paulo has $145 in a savings account earns 36 a week mowing lawns if Paulo says all his earnings after how many weeks will he have 433 saved.

Answer 1

It will take 8 weeks for Paulo to save 433

Explanation:

Write an equation, then solve it. Use slope intercept form for this linear equation.

433 is the total (y)

36 is the amount per week (m)

145 is what Paulo started with (b)

weeks worked is unknown (x)

Start with y=mx+b

Plug in numbers:

433=36x+145

Subtract 145 from both sides:

288=36x

Divide both sides by 36:

8=x This means it will take 8 weeks for Paulo to save 433
