Question

Jessica and Gabriella each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same store. Jessica spent $38 on 8 rose bushes and 2 geraniums. Gabriella spent $71 on 8 rose bushes and 5 geraniums. Find the cost of one rose bush and the cost of one geranium

Answer 1

Germanium's cost 11

Rose bush cost 2

Answer 2

38 = 8r+2g

71 =8r+5g

subtract the 2 equations

71 =8r+5g

38 = 8r+2g

------------------------

33 =3g

divide by 3

g=11

38 = 8r +2g

38 = 8r+2(11)

38 = 8r+22

subtract 22 from each side

16 = 8r

divide by 8

r=2

Germaniums cost 11

Rose bush cost 2
