Question

Josue is saving up to buy a new phone. He already has $100 and can save an additional $5 per week using money from his after school job. How much total money would Josue have after 4 weeks of saving? Also, write an expression that represents the amount of money Josue would have saved in ww weeks.

Answer 1

$120, 5w+100

Explanation:

Josue starts with $100 and earns $5 a week over 4 weeks. That means you multiply 5 by 4 to get $20 dollars earned over 4 weeks. Then you add that to how much money he already has 100+20=$120 after 4 weeks. To get an expression, we have to take the amount of weeks and multiply it by 5 to show the 5 dollars he earns every week (5w) and then add the 100 dollars he already has to it, which gives us 5w+100.
