At a concession stand, one person purchased 3 drinks and 3 soft pretzels. another person purchased a total of $9.00. another person purchased 4 drinks and 2 soft pretzels for a total of $8.50. what was the price of one soft pretzel?
me understand how to do this question, my teacher didn't really make sense of this.
the lesson is: application of system

$1.75

Step-by-step explanation:

Let x be the cost of 1 drink

Cost of 3 drinks = $3x

Cost of 4 drinks = $4x

Let y be the cost of 1 soft pretzels.

Cost of 3 soft pretzels=$3y

Cost of 2 soft pretzels=$2y

Now we are given that  One person purchased 3 drinks and 3 soft pretzels. Another person purchased a total of $9.00.

So, equation becomes :  --1

Now we are given that Another person purchased 4 drinks and 2 soft pretzels for a total of $8.50.

So, equation becomes : --2

Solving 1 and 2 graphically

Intersection point provides the  answer of the system of equations

Refer the attached graph

Intersection point : (1.25,1.75)

Hence the price of one soft pretzel is $1.75

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

answer: c

(2, -4)

goes 7 to the

(9, 4)
