Given:
Tony has $20
He wants to buy atleast 4 snacks.
Hotdogs cost (x) = $3
Peanuts cost (y) = $2
Explanation:
We can determine the number of snacks that Tony can buy and which kind by simply taking the proportion of the total money from the hotdogs cost. In order for Tommy to have at least 4 snacks, and consume all $20. We can find an even multiple of 3 taken from $3.
= (3)(4)
=$12
4 hotdogs for $12
= $20 - $12
= $8
Divide 8 by 2 since each peanut cost $2
= 8/2
= 4
4 peanuts for 8$
Final answer:
Tony can buy 4 hotdogs for $12 and 4 peanuts for 8$
