Cheryl wants to have $2300 in spending money to take on a trip to Disney World in three years. How much must she deposit now in
Savatey [412]

Use the compound amount formula:

$2,300 = P(1+0.02)^3.  Solve this for P:

P = $2,300 / (1.02)^3 =  $2167.34.

By depositing $2,167.34 now, Cheryl would have $$2300 after three years.

Answer:

The answers would be as follows:

3

3

1

1

Step-by-step explanation:

We can tell that the first two have an infinite number of solutions because when we try to solve, we get a true statement. The first one is done for you below.

-6x + 7 = -6x + 7 ------> Add 6x to both sides

7 = 7 (TRUE STATEMENT)

We can tell the next two have no solution due to the fact that they develop a false statement when trying to solve.

-3x + 7 = 3x + 7 ----> Subtract 7 from both sides

-3x = 3x ---> Divide by 3

-x = x (UNTRUE STATEMENT)
