Mike earns $6.50 per hour plus 4% of his sales enter an equation for mikes total earnings, e, when he works x hours and has a total of y sales, in dollars.

e= 6.50x + y 0.04

Step-by-step explanation:

Hi, to answer this question we have to multiply the number of hours he works (x) by the earnings per hour ($6.50), add the product of the total sales (y) and the percent of sales he gets in decimal form (0.04 = 4/100).

That expression must be equal to the total earnings (e)

Mathematically speaking:

e= 6.50x + y 0.04

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.

i think it is c, not positive though
