Question

A very, very hungry guy goes to a fast food place and orders 2 chicken sandwiches

and 4 tacos, at a total cost of $6.60. Three days later, he's ready to eat again. This
time, he buys 5 chicken sandwiches and 2 tacos, at a total cost of $9.30. Write and
solve a system of linear equations. Identify the cost of one chicken sandwich, and the
price of one taco.

Answer 1

Answer:Burgers are $1.50 and tacos are $0.90

Step-by-step explanation:Let b denote burgers and t denote tacos. Our equations are then:2b+4t=6.605b+2t=9.30Multiply bottom equation by 2 to get 10b+4t=18.60. Subtract the two equations to get:-8b=-12b=12/8=1.5Plug this back into either equation, I'll use the first one, 2(1.5)+4t=6.60. t=0.90.
