if melissa placed an order for garden gloves ($2.99 each), and rakes (for $16.99 each), and she ordered three times as many glov
es than rakes, how many rakes dis she purchase, if the sales total was $129.80?
1 answer:
G:$2.99
R:$16.99
For every 1R we have 3G.
1R+3G=$16.99+3($2.99)
So 1R+3G=$25.96
If we take $129.80÷$25.96, we get 5.
So let's try 5.
5R+15G=5($16.99)+15($2.99)
So 5R+15G=$129.80
