 find the price of each item. for example Todd bought 3 shrubs and 6 tomatoes for 87 dollars and Sara bought 7 shrubs and 5 tomatoes for 138 dollars.
***
let s=price of shrubs
let t=price of tomatoes
..
3s+6t=87
7s+5t=138
..
15s+30t=435 (mult. eq. by 5)
42s+30t=828 (mult. eq. by 6)
subtract
27s=393
s=14.56
6t=87-3s=87-43.67=43.33
t=7.22
price of shrubs=$14.56 each
price of tomatoes=$7.22 each
