As an instructor at a gym, Kato earns $15 per hour.
He is planning to deposit 40% of his hourly earnings into his savings account
40% *15 = $6
He has $362 in his savings account
He has to have $800 in his savings account
800-362=438
Let x be number of hours he has to work to add $438 to his account
6x =438
x= 73
Kato must work 73 hours to have $800 in his savings account.
