Question

Mrs. Lola and Mr. John bought tacos and burgers for lunch 2 days in a row. One day they bought 4 burgers and 3 tacos for $269, the next day they bought 5 burgers and 4 tacos for $347. How much does each taco and burger cost?​
Help please

Answer 1

Answer:

One burger is $35 and one taco is $43

Step-by-step explanation:

First you substitute:

4b + 3t = 269 => t = 269/3 - 4/3b

5b + 4t = 347 => b = 35

t = 269/3 - 4/3b

t = 269/3 - 140/3

t = 43
