Lauren coordinates a construction projects for a cement company. a government project requires constructing two rectangular concrete slabs of dimensions 24× 24× 1 feet. additionally, the company sends a 20% surplus of concrete to ensure the job can be completed. if a cement truck can carry a maximum of 8 cubic yards of cement, what’s the fewest number of trucks that lauren should send? a)1 b)2 c)3 d)4 e)5

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.

it is a secret for it not to be compromised sorry
