I am saving money for a new PS5. I already have $150 and I save $14 every week. Write an equation that shows how much I save (y) after x weeks.
BONUS: If a PS5 costs $500, how many weeks do I need to save?

Jalen is growing houseplants. He has some number of plants, but is not very good at it so he accidentally kills half of them. Then, to make up for it he adds 3 more to his collection. Now he has 7 total plants. Write and solve an equation to find out how many plants he started with.
x/2 + 3 = 7
x/2 =4
x = 8
He had 8 plants at the start
