Menendez has $55 in his savings account. He deposits $10 every week and doesn’t take any money out. He wants to save $135 to buy a used tablet. The equation 10w+55=135 can be used to determine the number of weeks, w, that Menendez needs to save money in order to buy the tablet. How many weeks will it take Menendez to save $135?

1 answer

To determine how many weeks it will take Menendez to save $135, we can solve the equation \(10w + 55 = 135\).

First, we will isolate \(w\) by subtracting 55 from both sides:

\[ 10w + 55 - 55 = 135 - 55 \]

This simplifies to:

\[ 10w = 80 \]

Next, we divide both sides by 10 to solve for \(w\):

\[ w = \frac{80}{10} = 8 \]

Thus, it will take Menendez 8 weeks to save enough money to buy the tablet.
