There asking for the equation, and the possible answers are
y = 2x + 6
y = −one halfx + 3
y = −one halfx + 6
y = 2x + 3
10 times 20,000 equals 200,000. So the answer is C, the value of the 2 is 10 times greater
1800×6.5%×30=b
b-1800=a
a) $1,710
b) $3,510
Neither Alex nor Jo are correct, because surface area is a 2-dimensional quantity, so it would be given in just square units, not linear nor cubic.
So the answer is D
