Answer:
D
Step-by-step explanation:
A proportional relationship is defined by a linear equation whose y-intercept is zero.
Thus, we immediately reject answers A, B, and C because all involve a non-zero y-intercept.
D is the correct answer. We combine the unit cost $1.75/lb with the shipping fee $0.16/lb, obtaining a unit cost of $1.91/lb. The desired linear equation with zero y-intercept is then
C(x) = ($1.91/lb)x, where x is the number of pounds of avocados sold.
C=2 and j=4
j+y=2(c+y)-7
j+y=2c+2y-7 and since j=4 and c=2 we have:
4+y=2*2+2y-7
y+4=2y+4-7
y+4=2y-3
-y+4=-3
-y=-7
y=7
So in 7 years Jenny will be 7 years younger than twice Chris' age.
check...
4+7=2(2+7)-7
11=2(9)-7
11=18-7
11=11
