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

Question

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?

Answer 1

To determine how many weeks it will take Menendez to save $135, we can solve the equation:

\[ 10w + 55 = 135 \]

First, subtract 55 from both sides of the equation:

\[ 10w = 135 - 55 \]

This simplifies to:

\[ 10w = 80 \]

Next, divide both sides by 10 to isolate \( w \):

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

So,

\[ w = 8 \]

Menendez will need to save for 8 weeks to have enough money to buy the tablet.
