Anjali spent $195 on 11 rose bushes and 14 geraniums.Joe spent 140 on 14 rose bushes and 7 geraniums.What is the cost of one rose bush and the cost of one geranium?

Respuesta :

Answer:

roses cost 5 geraniums cost 10

Step-by-step explanation:

rose=x

geraniums=y

11x+14y=195

14x+7y=140

Multiply the top by -7 and the bottom by 14 so geraniums(y) cancels out and you can find rose(x)

-77x-98y=-1365

196x+98y=1960                 y cancels out

119x=595

------  -----

119   119

rose(x)=5   insert 5 for x to find y (geraniumns)

11(5)+14y=195

55+14y=195

             -55                

14y=140                      

-----   -----                              geraniums(y)=10

14      14
