Jackie buys 3 hot dogs and 1 pretzel from a restaurant for $12.25. Sylvia buys 2 hot dogs and 4 pretzels from the same restaurant for $16.50. Part A

Which system of equations can be used to determine the price of a hot dog, h, and a pretzel, p, at the restaurant?

​​​​​​2h + 1p = 12.25

3h + 4p = 16.50

​​​​​​ 2 h + 1 p = 12.25 , , 3 h + 4 p = 16.50,

2h + 1p = 12.25

3h + 4p = 16.50

2 h + 1 p = 12.25, , 3 h + 4 p = 16.50,

2h + 4p = 12.25

3h + 1p = 16.50

2 h + 4 p = 12.25 , , 3 h + 1 p = 16.50,

3h + 1p = 12.25

2h + 4p = 16.50

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
