The ratio of skiers to snowboarders is 5 to 2. if 210 skiers rode the chairlift in the last hour, how many snowboarders rode the chairlift during that same time?

[a] write a proportion that is defined by this situation.

[b] explain how the cross product is used to solve the problem.

[c] answer the question.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
