profit = revenue - expenses
Filling in the given values, where n is the number of necklaces Sam must sell ...
... 1000 = 10n - (5n +5000)
... 6000 = 5n . . . . . . collect terms, add 5000
... 1200 = n . . . . . . . divide by 5
The appropriate choice is
... D. 1200
Answer:
n = 3
Step-by-step explanation:
plug in 3 for n in the equation:
Numerator: n + 1 = 3 + 1 = 4
Denominator: 2^n = 2^3 = 2 * 2 * 2 = 4 * 2 = 8
Simplify the fraction. Divide common factors from both the numerator and denominator:
(4/8)/(4/4) = 1/2
1/2 = 1/2 ∴ n = 3

X + y= 30
.05x + .10y= 1.65
n + d = 30
5n + 10d = 165
-5n - 5d = -150
5n + 10d = 165
5d = 15
d = 3 dimes
n + 3 = 30
n= 27 nickels
