In the “I love unusual pets” club, 7 members owned snakes, 13 owned iguanas, and 5 owned potbellied pigs. Three people didn’t own any unusual pets, and one person owned a snake, iguana and a potbellied pig. If no member owned only two of these pets, how many members were there in all?

I think it would help if you put some more info. This question is a little confusing. I hope you take my opinion into consideration. Thanks!

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.
