Jonah wants to buy a new tablet. He starts to save up with the $50 he received for his birthday. He gets an allowance of $12 each week from his parents. Jonah needs to save a total of $110 to buy the tablet he wants.

Question

Which equation can Jonah use to find w, the number of weeks he should save to reach his goal?
12(w + 50) = 110
50(w + 12) = 110
50w + 12 = 110
12w + 50 = 110

Answer 1

To find the number of weeks \( w \) that Jonah should save to reach his goal of $110 for the tablet, we can set up an equation based on his initial savings and his weekly allowance.

Jonah starts with $50 and receives $12 for each week he saves. After \( w \) weeks, his total savings will be the initial $50 plus the savings from his weekly allowance, which can be expressed as:

\[ 50 + 12w \]

He wants this total to equal $110:

\[ 50 + 12w = 110 \]

Therefore, the correct equation Jonah can use is:

\[ 12w + 50 = 110 \]

So the answer is:

\[ 12w + 50 = 110 \]
