Your family went to eat at a restaurant and the bill was $32.50. you want to leave a 15% tip. what is the total amount you will pay? (round to the nearest cent)

There are two ways you can find the total.

Either you can do total + total*rate

OR

Total * (1+rate)

Since the second involves less steps, I will be using the second below.

Since it is money, it is implied to round to the nearest hundreth (nearest cent).

You would pay $37.38

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
