Sal is saving for a new bike that will cost him $150. He currently has $35 and can save $23 per week. How many weeks will it take him to earn enough money for the bike?

Let w equal the number of weeks that Sal saves his money. Select an equation and solution that matches this situation.

23w+35=150; Sal will have enough money in 5 weeks.
23w+35=150; Sal will have enough money in about 8 weeks.
150−23w=w; Sal will have enough money in 24 weeks.
35w+23=150; Sal will have enough money in about 5 weeks.
35w+23=150; Sal will have enough money in about 138 weeks.

We can see 35 as the starting value since he already has that amount when he started saving up money. We can subtract it (150 - 35 = 115). Then we can divide (115 / 23 = 5). It took Sal 5 weeks to save enough money for the bike. The first option makes the most sense because the expression can be solve to find how many weeks he save up his money.
