Answer:

Step-by-step explanation:

Given:

Variables:

Let R = rose bush cost and G = geranium cost

System of Equations

I. 10R + 3G = 86

II. R + 8G = 24

solving equation i and ii simultaneously,

R = 24 - 8G

10 (24 - 8G) + 3G = 86

240 - 80G + 3G = 86

240 - 77G = 86

G = (86 - 240) / (- 77)

= $2

Substituting V = 2 into the equation ii,

R + 8g = 24

R + 8(2) = 24

R = 24 - 16

R = $8
