natima [27]
If he makes $8 per hour while babysitting, then if he works 3 hours - then he’d get $24 for babysitting.

He still has to make $176.
He can work 18 hours, if he uses up 3 hours babysitting, he has 15 hours left.

15 hours times $15 = 225 (too much)
12 hours times $15 = $180 ( he saves three hours)

He has to do 12 hours of life guarding to meet his goal - he will have three spare hours.

Sorry if I’m wrong, I think I’m right tho
