Liza gets paid $5.50 an hour to babysit her little cousins. Last weekend, she watched them for three hours on Friday, nine hours on Saturday, and seven hours on Sunday. How much money does her aunt owe her for her babysitting services?

104 dollars and 50 cents

Step-by-step explanation:

It's really simple. You just find the total of the hours and multiply it by how much each costs. Simple, right? Let's go through it together.

Since we want to know the total, we do this: 7+9+3

And we know each hour is worth 5 dollars and 50 cents.

So let's make the total "X". Still with me? Let's finish.

So: (7+9+3) * 5.50 = X

     (19) * 5.50 = X

     104.50 = X

ask the math teacher she or he would know lol.

step-by-step explanation:

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
