Mari wants to save up to pay for her first car. She estimates that she will need to save at least $7,500 for her first car. Mari makes $800 a month but has to pay her friend $50 each month to car pool to work. How long will it take Mari to save $7,500?

Step-by-step explanation:

800 - 50= 750

so she need 10 months to save $7,500

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
