Answer:
3.75 or 3 3/4
Step-by-step explanation:
A = 210 + 20(h - 7) <== ur equation
if she earns 410 tutoring...
410 = 210 + 20(h - 7)
410 = 210 + 20h - 140
410 = 20h + 70
410 - 70 = 20h
340 = 20h
340/20 = h
17 = h <=== she spent 17 hrs tutoring
Y = 3/2x + b
4 = 3/2(-10) + b
4 = -15 + b, b = 19
Y = 3/2x + 19
<u>Answer:</u> $42546.9 will be the earning in 4 years.
<u>Step-by-step explanation:</u>
The equation for compound interest follows:

where,
A = total amount
P = Principle amount
r = rate of interest
n = number of years
We are given:
Earnings earned per month = $3250
Earnings earned per year = ($3250 × 12) = $39000
The values become:

Putting values in above equation, we get:

Hence, $42546.9 will be the earning in 4 years.
