2 vases and 8 bunches of flowers cost $15.
20 vases and 5 bunches of flowers cost $25.
How much does each item cost?
Let the price of a single vase =V
let the price a single bunch of flowers =F
2V + 8F = 15........................(1)
20V + 5F=25........................(2)
Now, you have 2 simultaneous equations. Can you solve them?
