Accepted Solution

A:
Answer: Cost of a single Mucho beef burrito: [tex]\$5.5[/tex] Cost of a double Mucho beef burrito: [tex]\$6.5[/tex]Step-by-step explanation: The exercise is: "The Little Mexican restaurant sells only two kinds of beef burritos: Mucho beef and Mucho Mucho beef. Last week in the restaurant sold 16 orders of the single Mucho variety and 22 orders of the double Mucho. If the restaurant sold $231 Worth of beef burritos last week and the single neutral kind cost $1 Less than the double Mucho, how much did each type of burrito cost?" Let be "x" the the cost in dollars of a single Mucho beef burrito and "y" the cost in dollars of a double Mucho burrito. Set a system of equations: [tex]\left \{ {{16x+22y=231} \atop {x=y-1}} \right.[/tex] To solve this system you can apply the Substitution Method: 1. Substitute the second equation into the first equation and solve for "y": [tex]16(y-1)+22y=231\\\\16y-16+22y=231\\\\38y=231+16\\\\y=\frac{247}{38}\\\\y=6.5[/tex] 2. Substitute the value of "y" into the second equation and evaluate in order to find the value of "x": [tex]x=6.5-1\\\\x=5.5[/tex]
