Question

jane sells 8 times as many Volvos as Melissa. If the difference in the sales is 35, how many cars did Jane sell?

Answer 1

make two equations:
x = jane
y = melissa

x = 8y
35 = x + y

Answer 2

so subsititute the 8y into the second equation for x

Answer 3

@jazy it should be "35 = x - y" in 2nd eqn, shouldn't it?

Answer 4

Oh yeah! thanks for correcting me:)

Answer 5

so we still substitute the value of x into the second equation i think:
35 = (8y) - y
35 = 8y - y
35 = 7y
/7
y = 5
now you can find x by putting 5 in for the y-value

Answer 6

35 = x - 5
Once you figure out what x is you know how many cars jane sold:) I leave it to you!
