90 points. Foolish and incomplete answers are going to be deleted. Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 3 liters of natural oil for every 5 liters of synthetic oil. If 736 liters of natural oil are used, how many liters of Petrolyn oil will be made?

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

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.

b, i believe, but not sure.
