Joe buys a sandwich from a deli for $8. He leaves a 15% tip. What is the total amount he paid for his lunch?

9.20

Step-by-step explanation:

8.00 x 15% = 1.20

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
