a college professor making $2,133.91 per month has deducted from her check $309.20 for federal income tax, $172.53 for retirement, and $42.54 for state income tax. how much does the professor take home after the deductions have been taken from her monthly income?

72 is the answer to this problem

idk lol xd

step-by-step explanation:

ez do it yourself lazy

you can't solve x because it is 2 linear equation and you only have one equation

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
