3 x 18 = $54
2 x 3.99 = $7.98
1 x 45.00 = $45.00
Add: $54 + 7.98 + 45 = $106.98
Multiply: $106.98 x 0.085 = 9.093
Add: $106.98 + $ 9.09 = $116.07

Step-by-step explanation:
15a)
Subtract both sides by 21
15b)
7 and -3 multiply to -21 and add to 4
The factors are (x+7)(x-3)
15c)
x+7 =0
x=-7
x-3=0
x=3
Answer:
x = 4
y = 3
Step-by-step explanation:
2x - 3(x - 1) = -1
2x - 3x + 3 = -1
-x + 3 = -1
- 3 - 3
(-1) -x = -4 (-1)
x = 4
y = 4 - 1
y = 3
