A jet ski company charges a flat fee of $26.00 plus $3.25 per hour to rent a jet ski. Another company charges a fee of $24.00 plus $3.50 per hour to rent the same jet ski.

Using a graphing calculator, find the number of hours for which the costs are the same. Round your answer to the nearest whole hour.

26.00+3.25x=24.00+3.50.
The Answer is 8!

X Lbs. of jelly beans.
2x Lbs. of gummy candy.
9-(x+2x) = (9-3x) Lbs. of hard candy.

3*x + 2*2x + 3*(9-3x) = 23.00.
3x + 4x + 27-9x = 23
X = 2.0 Lbs. of jelly beans.

2x = 2 * 2 = 4 Lbs. of gummy candy.

9-3x = 9-3*2 = 3 Lbs. of hard candy.

For the gummy equation you dont really need to do anything. Just look and see which answer has two times as many gummies as jelly beans. The answer is B.
