To find out how many weeks it will take Menendez to save $135, we can solve the equation given:
\[ 10w + 55 = 135 \]
- First, subtract 55 from both sides of the equation:
\[ 10w + 55 - 55 = 135 - 55 \] \[ 10w = 80 \]
- Next, divide both sides by 10:
\[ w = \frac{80}{10} \] \[ w = 8 \]
So, it will take Menendez 8 weeks to save $135.
