The Garden Wall A homeowner is going to build the raised bed garden shown in the plan, against an
existing garden wall. The homeowner will build the new wall by stacking concrete blocks
without mortar, and then fill in the walled space with garden soil. The concrete blocks have
dimensions 8 inches x 8 inches x-T6 inches. The wall will be capped by capstones that have
dimensions 8 inches x 2 inches x 16 inches. Concrete blocks cost $1.50 each, capstones
cost $1.00 each, and garden soil costs $36 per cubic yard. The homeowner will do all the
work and will buy materials. How much will they cost?

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.

just sum

10 + 10 = 20
