A snow cone consists of a paper cone completely filled with shaved ice and topped with a hemisphere of shaved ice. The inside

diameter of both the cone and the hemisphere is 8.3 centimeters. The height of the

cone is 10.2 centimeters. The desired density of the shaved ice is 0.697 g/cm^3, and

the cost, per kilogram, of ice is $3.83. Determine the cost of the ice needed to

make 50 snow cones.

step-by-step explanation:

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.

answer: 0.26
