Answer:
x = - 4
Step-by-step explanation:
-79 = 7x + 3(4x - 1)
-79 = 7x + 12x - 3 Distribute 3 to the paranthesis
-79 = 19x - 3 Add like terms
-76 = 19x Add 3 to both sides
- 4 = x Divide 19 to both sides
Answer:
3,378.70
Step-by-step explanation:
First, find the total amount Henry spends a month. 25.30 for printer ink and 52 for advertising. 25.30+52=$77.30.
Subtract what he has spent from what he has made.
3,456-77.30=3,378.70
That is his profit.
