The cost of selling handmade cards is $20.00 each, and the cost of selling bookmarks is $2.50 each.
Let x be the quantity of bookmarks Mark must sell.
To find the total sales, we need to sum the cost of the handmade cards and the cost of the bookmarks:
Total sales = (Cost of handmade cards) + (Cost of bookmarks)
Since Mark must sell at least one handmade card, the cost of the handmade cards is $20.00:
Cost of handmade cards = $20.00
The cost of the bookmarks is $2.50 each, and Mark must sell x bookmarks:
Cost of bookmarks = $2.50 * x = 2.50x
Therefore, the total sales can be represented as:
Total sales = $20.00 + 2.50x
Mark wants his total sale to reach a minimum of $90.00, so we can write the inequality:
Total sales ≥ $90.00
Replacing the total sales expression, we have:
$20.00 + 2.50x ≥ $90.00
This inequality represents the various quantities of bookmarks (x) Mark must sell.
Mark runs a stall selling handmade cards and bookmarks.
Each handmade card cost $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?
