A) The total cost for 8 bracelets, including the shipping was $ 54. The shipping charge was $ 6. Define your variable and write an equation that models the cost of each bracelet.
The first thing we must do for this case is define variables:
y = total cost
x = Cost of bracelets
Writing the equation we have:
y = ((54-6) / (8)) x + 6
Rewriting:
y = (48/8) x + 6
y = 6x + 6
The total cost is $ 54, therefore:
54 = 6x + 6
Answer:
An equation that models the cost of each bracelet is:
54 = 6x + 6
B) Use the equation you have written in part A to determine the cost for each bracelet. Please show the algebraic steps that it takes to find the answer, and please provide the conclusion.
We have the following equation:
y = 6x + 6
The cost of each bracelet is given by the slope of the line:
$ 6
For x = 8 bracelets we have:
y = 6 (8) + 6
y = 48 + 6
y = $ 54
Answer:
the cost for each bracelet is:
$ 6
