Let [math]h[/math] represent the total number of hats. Write an expression in terms of [math]h[/math] for the total number of items they have to sell.
The owner of the stand pays $8 for each hat, $0.10 for each post card, and $0.50 for each magnet. Write an expression for the total cost of the items.
The souvenir stand sells the hats for $11.75 each, the postcards for $0.25 each, and the magnets for $3.50 each. Write an expression for the total amount of money they would take in if they sold all the items.
Profits are calculated by subtracting costs from income. Write an expression for the profits of the souvenir stand if they sell all the items they have. Use properties to write an equivalent expression with fewer terms.
Write an equation that represents this situation.
How many of each item does the souvenir stand sell? Explain or show your reasoning.
[size=150]Basic crochet stitches are called single, double, and triple. Jada measures her average stitch size and sees that a “double crochet” stitch is not really twice as long; it uses [math]\frac{1}{2}[/math] inch less than twice as much yarn as a single crochet stitch. Jada’s “triple crochet” stitch uses 1 inch less than three times as much yarn as a single crochet stitch.[/size][br][br]Write an expression that represents the amount of yarn Jada needs to crochet a scarf that includes 800 single crochet stitches, 400 double crochet stitches, and 200 triple crochet stitches.
Write an equivalent expression with as few terms as possible.
If Jada uses 5540 inches of yarn for the entire scarf, what length of yarn does she use for a single crochet stitch?
