three-quarters of that for the snowboard.
a) Write an inequality that can be used to determine the minimum number of weeks Sarah
needs to babysit to have enough money to purchase the snowboard.
b) Determine and state the minimum number of full weeks Sarah needs to babysit to have
enough money to purchase the snowboard.

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.
