Answer:
Step-by-step explanation:
Let p and h represent the prices of 1 pizza and 1 hotdog.
5p +6h = 43
6p +5h = 45
Adding the two equations together, we get ...
11p +11h = 88
p + h = 8 . . . . . . divide by 11
Subtracting 5 times this equation from each of the above, we get ...
(5p +6h) -5(p +h) = (43) -5(8)
h = 3 . . . . cost of a hotdog
and
(6p +5h) -5(p +h) = (45) -5(8)
p = 5 . . . . cost of a pizza
One pizza costs $5; one hotdog costs $3; one pizza and one hotdog costs $8.
