Shelly wants to earn at least $500 this week. she made $45 babysitting and earns $12.50 per hour at a grocery store. How many hours does she need to work at the grocery store to meet her goal?

36.4 hours

Step-by-step explanation:

500=45+12.50x

455=12.50x

36.4=x

She has to work at least 37 hours at the grocery store to meet her goal.

Step-by-step explanation:

y=mx+b

500=12.50x + 45

when you solve this equation you get 36.4 which rounds to 37.

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

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.
