$0.75.

Step-by-step explanation:

We have been given that Janet's dinner costs $7.50. She wants to leave a 10% tip. We are asked to find the amount of tip.

The amount of tip will be equal to 10% of $7.50.

Therefore, Janet should leave $0.75 extra for the tip.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

the first one, all those points on the line just make a strait line.
