Estimate:
Bill = $20 approximately.
5% tax on $20 = 20/20=$1
20 % on ($20) = $4
Total cost = $20+1+4 = $25
Total bill = $25 approximately.
Exact calculations
bill = 19.68
tax 5% = 0.98
Tip 20% of original = 3.94
Total bill = 19.68+0.98+3.94 = 24.60
The rate of change is 500.
.08 , .6, 4, 20
.08 has a hundredth value, while .6 has a tenth value. You could also look at .6 as .60 which might help.
Answer: y = 5x + 10
Step-by-step explanation:
y= 5x + 10
THINK ABOUT IT! if 5 is for EACH additional session and x is equal to the NUMBER OF SESSIONS...... then 5 times x will give you the cost for each additional session, but NOT INCLUDING THE 10 FOR THE FIRST SESSION. so simply just do 5x + 10 and y is the total cost so
y = 5x + 10
