Which statement about the student's answer is correct? a company spent $5,884 in one month to advertise its new website. the company figured that it would need to spend $3,185 the next month on the website. how much would the company end up spending for both months? a student answered that the company will spend $2,699 for both months. a. the answer should be about $3,000. the student's answer is close to the estimated answer. b. the answer should be about $8,000. the student's answer is not correct. c. the answer should be about $9,000. the student's answer is not correct. d. the answer should be about $10,000. the student's answer is not correct.

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.

the answer is b
