Answer:

x=$2.50, y=$4.00

Step-by-step explanation:

Let x=cost of the water slide

Let y=cost of the ferris wheel

System of equations:

3x+3y=19.50

2x+3y=17.00

Subtract the 2nd from the 1st to get:

x=2.50

Now plug into first equation to get:

3(2.50)+3y=19.50 so y=4.00

Check in 2nd equation:

2(2.50)+3(4) = 5+12 = 17

Answer: c) $30,799.45

Step-by-step explanation:

Assuming there are 52 weeks in a year, the rate and time would be converted to;

Rate = 8%/52 = 8/52%

No. of periods = 9 years * 52 weeks = 468

The amount Mr Mantle would have is;

= 15,000 * ( 1 + 8/52%) ⁴⁶⁸

= $30,799.45276

= $30,799.45
