14 Kelvyn was hired to wash windows at $40 a day. Hopps was hired to dry windows according to the following plan: $0.01 for the first day, $0.02 for the second day, $0.04 for the third day, and so on, with each day doubling the amount earned on the previous day. After 20 days, they both quit. Who earned more money? How much more?​

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

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.

10 you would take 50/ .2
