Diragio Lawn Care cuts 42 lawns every week. Each lawn uses of a tank of gas when it is cut (on average).
Part A: If the lawnmower had no gas at the start of the
week, how many times would it have to be completely
filled during the week? Show your work.
Part B: The cost for a full tank of gas in the
lawnmower is $20. How much does it cost (in
lawnmower fuel only) to mow one average lawn?
Show your work.

answer:  

123455421

step-by-step explanation: easy

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.
