Sonja [21]

Answer:

Number of Chicken Burritos purchased=7

Number of Cheesy Gordita Crunch purchased=6

Step-by-step 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)

$0.6x=4.2$

$x=\frac{4.2}{0.6}$

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

Answer:

x = -12

y = 3

Step-by-step explanation:

$1/2x + 6(x+15) = 12\\1/2x + 6x + 90 = 12\\6\frac{1}{2} x + 90 = 12\\6\frac{1}{2} x= -78\\x = -12$

$y = x + 15\\y = -12 + 15\\y = 3$
