Wendy needs to babysit for h hours to earn enough money to buy the MacBook.
● The MacBook costs $860.
● Wendy already has $160 saved.
● She babysits for $20 per hour.
Using the information above, write an equation that will represent the number of hours h, that Wendy needs to work in order to buy a new MacBook.
860 = 160 + 20h
