Question

At Taco Bell, I made a large purchase of 13 items that cost a total of $28.17. If Chicken Burritos cost $1.89 each and a Cheesy Gordita Crunch costs $2.49, determine how many of each that I purchased.

Answer 1

Number of Chicken Burritos purchased=7

Number of Cheesy Gordita Crunch purchased=6

Explanation:

Let x be the number of Chicken Burritos and y be the number of Cheesy Gordita Crunch.

Total number items purchased=13

Total cost of 13 items=$28.17

Cost of each Chicken Burritos=$1.89

Cost of each Cheesy Gordita Crunch=$2.49

We have to find number of each items purchased.

According to question

`x+y=13`.....(1)

`1.89x+2.49y=28.17`...(2)

Equation (1) multiply by 2.49 and then subtract equation (2) from (1)

`0.6x=4.2`

`x=(4.2)/(0.6)`

x=7

Substitute x=7 in equation (1)

`7+y=13`

`y=13-7=6`

Number of Chicken Burritos purchased=7

Number of Cheesy Gordita Crunch purchased=6
