Answer:
19
Step-by-step explanation:
8 x 4 = 32
32 + 6 = 38
38 / 2 = 19
The function can use all values of x which means x is in between -inf and +inf. The first option expresses this.
Your equation would be 2x - 12 + 3x - 15 = 23
Combine like terms and solve for x
If the total bill is $85, and you want to leave a 15% tip, then you can calculate it as follows:
85 * 15%
= 85 * 15/100
= 85 * 0.15
= 12.75
The amount that should be left as a tip is D. $12.75.
