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?
The total sales from selling handmade cards can be represented as 20 times the number of cards sold, which is 20x.
The total sales from selling bookmarks can be represented as 2.50 times the number of bookmarks sold, which is 2.50x.
To find the inequality representing the various quantities of bookmarks Mark must sell, we need to set the total sales greater than or equal to $90.00:
20x + 2.50x ≥ 90.00
