Answer:

$1,053.50

Step-by-step explanation:

First you need to multiply $33.30 by 30 so you can figure out how much she'll save over the next 30 weeks. You will get $999. Then you add $54.50 and $999 together to get 1,053.50.

I have to pay my friend $1 increased by 50% each day for 20 days. How much do I have to pay him at the end of the 20 days.
Radda [10]

So for this, you'll be using an exponential equation, which is y=ab^x (a = initial value, b = growth/decay).

Since you start off paying your friend $1, that will be your initial value. And since this is a 50% increase, you are to add 1 and 0.5 together (50% in decimal form), which is 1.5. That will be your b variable. And since # of days is the independent variable, that will be your x variable.

Using the previous info, this is our equation: y = 1(1.5)^20 . From here we can solve for the total cost (y).

Firstly, solve 1.5^20: y = 1(3325.26)

Next, multiply everything on the right side of the equation, and your answer will be (rounded to the hundreths): y = 3325.26

In context, at the end of the 20 days, you have to pay your friend $3325.26.
