Makayla wants to buy a carton of juice. she could buy a 48 ounce container for $2.88 or a 64 ounce container for $3.52.

part a: what is the cost per ounce of the juice in the 48 ounce container?

part b: what is the cost per ounce of the juice in the 64 ounce container?

part c: which container is the better buy? justify you answer.

show work.

answer: add the !

step-by-step explanation: then we will answer

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.
