Question

You and your friend go to a taco truck for lunch. You order 3 soft tacos and 3 burritos and spend $11.25. Your friend orders 4 soft tacos and 2 burritos and spends $10.00.

Answer 1

Answer: See explanation

Explanation:

Let soft tacos be x

Let burritos be y

3x + 3y = 11.25 ......... i

4x + 2y = 10.00 ......... ii

Multiply equation I by 4

Multiply equation ii by 3

12x + 12y = 45 ....... iii

12x + 6y = 30 ....... iv

Subtract iv from iii

6y = 15

y = 15/6 = 2.5

A burrito cost $2.50

Since 3x + 3y = 11.25 .

3x + 3(2.50) = 11.25

3x + 7.50 = 11.25

3x = 11.25 - 7.50

3x = 3.75.

x = 3.75/3

x = $1.25

A soft tacos is $1.25
