Max makes a scale drawing of the distance between Salt Lake City and Arizona. The distance between Salt Lake City and Arizona is 21 cm on the scale drawing. If each 7cm on the scale drawing equals 250 kilometers, how far apart are they actually?

Actual distance = 750 km

Step-by-step explanation:

Given:

Scale drawing of distance = 21 cm

Scale ; 7 cm = 250 km

Find:

Actual distance

Computation:

Actual distance = 21[250/7]

Actual distance = 3[250]

Actual distance = 750 km

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.
