Rowan has $60. He wants to leave a 20% tip on his restaurant bill. His restaurant bill is $52.22.

Step-by-step explanation:

20% tip on 52.22 is 10.44

52.22*0.2=10.44

I don't think he has enough to do it though

52.22+10.44=62.664

He doesn't have enough (2.66 dollars short) Max percentage: 14.9%

Step-by-step explanation:

If Rowan has $60 dollars and wants a 20% tip. He would need to multiply the restaurant bill by 6/5, of if easier 120%

$52.22 x 120% = 62.66 dollars.

62.66 - 60 = 2.66. Therefore, Rowan CANNOT pay off a 20% tip and has $2.66 short.

Now, if we wanted to calculate which percent he can pay at max we look at 60/52.22.

This will give us 1.14898. Because of this, we can determine what percent Rowan can pay at max. 1.14898 - 1 = 0.14898.

Therefore, converting to percent, he can pay 14.9%(rounded)
