Question
Mark runs a stall selling handmade cards and bookmarks.
Each handmade card costs $20.00.
Each bookmark costs $2.50.
Mark wants his total sales to reach a minimum of $90.00 through the sale of at least one handmade card and several bookmarks. What inequality represents the various quantities of bookmarks (x) Mark must sell?
To represent the various quantities of bookmarks Mark must sell, we can set up the following inequality:
2.50x + 20.00 ≥ 90.00
This inequality states that the total sales from selling the bookmarks (2.50x) and the handmade cards (20.00) must be greater than or equal to $90.00.
