Equation : 3s + 4p = $26
Answer : 2 sodas and 5 bags of popcorn.
The equation would be 3s + 4p = $26. 3s is the $3 for every soda and 4p is $4 for every bag of popcorn.
Shana bought 2 sodas and 5 bags of popcorn. 3 x 2 is 6 and 5 x 4 is 20 which would equal $26. They also equal to the 7 things because of the 2 sodas and 5 bags.

Answer:

6,000 total items

Step-by-step explanation:

3*600=1800 (total juice)

2*600=1200 (total fruit)

2*600=1200 (total burritos)

2*600=1200 (total doritos)

1*600=600 (total milk)

1800+1200+1200+1200+600=6000
