Question

As a fundraiser, a school club is selling bracelets. The manufacturer charges a $25 set-up fee, plus $0.50 for each bracelet. Write a linear equation for the cost y in dollars to make x bracelets.

Answer 1

y=.5x+25

Explanation:

+25:y-intercept or fee

0.5x: commission per item sold; varying depending on the quantity sold.

Answer 2

0.5x + 25

Explanation:

We know that the y axis is the cost in dollars and the x axis is the number of bracelets. The number before x is the cost per bracelet. Since each bracelet costs $0.5 to make, simply make the slope 0.5. The manufacturer has a set-up fee, meaning before they even begin making bracelets, they need $25. The y-intercept is the $25 set-up fee. The full equation would be 0.5x + 25.
