Coach Thomas brings his baseball team to get ice cream after each Friday night game. Last week, he purchased 9 cones and 8 cups of ice cream and payed $53.50. This week he purchased 6 cones and 11 cups of ice cream and paid $51.25. Write and solve a system of linear equations to determine the cost of each cone and each cup.

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.
