Answer:
2 solutions
Step-by-step explanation:
Set up a system of equations. The absolute value produces two equations because one answer will be negative and the other positive.
d + 4 = -9
d + 4 = 9
So...
d = -13
d = 5
Answer: 1.25n
=======================================================
Explanation:
Erica sells bracelets for $2 each. If she makes and sells n of them, then she gets 2n dollars of revenue.
Making n bracelets cost her a total of 0.75n dollars because each bracelet costs 0.75 dollars, or 75 cents.
Subtract the revenue and cost to get the profit
profit = revenue - cost
profit = 2n - 0.75n
profit = (2-0.75)n
profit = 1.25n
The expression 1.25n means that she earns $1.25 in profit per bracelet sold.
