Plastics made up an estimated 390,000 tons of municipal solid waste (msw) generated in the united states in 1960. the quantity has increased relatively steadily to 31.8 million tons in 2011. as a percentage of msw generation, plastics were less than 1% in 1960, but had grown to 12.7% of waste in 2011. the overall amount of plastics recovered for recycling is relatively small. in 2011 it was 8.3% of all plastic waste. however, the recovery of some types of plastic containers is more significant. how many million tons of plastic waste were recovered for recycling in 2011?

B.

Step-by-step explanation:

do the math lil bruh

a

b

d

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.
