Question 512021: if 5 burritos and 3 tacos cost $20.25 and 2 burritos and 4 tqacos cost $13, how much does it cost for each burrito and each taco? Answer by oberobic(2304) (Show Source):
You can put this solution on YOUR website! 5b + 3t = 20.25
2b + 4t = 13
.
multiply the first equation by 4, the second by 3, and subtract the second.
.
20b + 12t = 81
6b + 12t = 39
---------------
14b = 42
.
b= $3
.
2*3 + 4t = 13
4t = 7
t = 7/4
t = $1.75
.
Check to see if the other equation is right.
.
5*3 + 3*1.75 = ??
15 + 5.25 = 20.25
Correct.
.
Answer: burrito = $3.00, taco = $1.75
.
Done.
