Emma doesn’t have $300 now, but she plans to get a job when she gets to college. she wants to find out how much it will cost her if she doesn’t pay off her credit card until after college. find how much she’ll owe in four years.

$528 dollars.

Step-by-step explanation:

In the USA The average credit card interest rate is 19% per year.

Emma borrows a quantity P=300.

After each year that goes on Emma has owns extra the 18% of P. Hence, the first year she owns

the second year, she owns

and so on, after n years she own

Since she wants to pay after the fourth year college, she will pay back

dollars.

the graph on the bottom right

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
