Javier works in a photo lab and needs to make a reduced copy of a photograph that is 8 inches long. the customer wants the copy to have a length of 4.5 inches. each time he presses the reduce button on the copier, the copy is reduced by 12%. javier and his boss had an argument, because javier claimed that pressing the button 5 times would be enough to fulfill the customer's request. his boss said that pressing the button 5 times would result in a length less than the desired 4.5 inches. which of the following conclusions can be made? javier is correct and he should press the button five times javier's boss is correct and he should press the button five times. javier is correct and he should not press the button five times. javier's boss is correct and he should not press the button five times.

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

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.
