This is the answer!! Also I use Photomath to help with my hw!
Answer:
A: E = 0.05t +56
B: $73.50
C: $60.05
Step-by-step explanation:
A) I'll just explain the equation in one go
Equation: E = 0.05t + 56
0.05 - This is meant to represent the 5% of tips
5% = 5/100
5/100 = 0.05
56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%
B+C) Since we already have the equation set up, we just need to plug in the variable, t.
B) E = 0.05(350) + 56
= 17.5 + 56
= 73.50
C) E = 0.05(81) + 56
= 4.05 + 56
= 60.05
Hope that does something to help, even though this was posted a while ago
Answer:

Step-by-step explanation:
Average cost = total cost/number of items = (35k² + 29k + 6)/(5k + 2)
Perhaps the best way to solve this problem is to use long division.
<u> 7k + 3 </u>
5k + 2)35k² + 29k + 6
<u>35k² + 14k</u>
15k + 6
<u>15k + 6</u>
0
Thus,

The average cost per item is
.
Answer:
6/10 for event A or 3/5 reduced
5/10 for event B or 1/2 reduced Hope that helps!
