Answer:
Therefore, the burritos cost $3.50 each and the tacos cost $2.50 each.
I hope this helps!
Step-by-step explanation:
Let x denote the price of the burrito and y denote the price of the taco.
Note that two burritos and five tacos cost 2x + 5y and five burritos and two tacos cost 5x + 2y. Since, they cost $19.50 and $22.50, respectively:
2x + 5y = 19.5. . . . . . . . . . . . . . . . . . . . .(1)
5x + 2y = 22.5. . . . . . . . . . . . . . . . . . . . .(2)
Multiplying (1) by 5:
5(2x + 5y) = 5(19.5)
==> 10x + 25y = 97.5. . . . . . . . . . . . . . . . .(3)
Multiplying (2) by 2:
2(5x + 2y) = 2(22.5)
==> 10x + 4y = 45. . . . . . . . . . . . . . . . . . .(4)
Subtracting (4) from (3):
(10x + 25y) - (10x + 4y) = 97.5 - 45
==> 21y = 52.5
==> y = 2.5.
Substituting y = 2.5 in (4) gives:
10x + 10 = 45 ==> x = 3.5.
The answer is -2. I hope my work helps.
