Please Help me! If the sales-tax rate is 8%, how much will the total cost of a purchase of $200 be?

216

Step-by-step explanation:

because 200 times 8 percent = 16 so then you add 16 too 200 and get 216.

a. is correct

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.
