Answer:
Cost of procedure is $45
Step-by-step explanation:
In this question, we are concerned with finding the cost of the procedure, given the tip amount and the percentage of which it is of the procedure cost.
From the question, we are told that the cost of the procedure is b
Mathematically, 12% of b = tip
Thus,
12/100 * b = 5.4
12b = 5.4 * 100
12b = 540
b = 540/12
b = $45
21+21+9+9=
2(9+21)=

We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years
In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.
Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
Answer:
24 pages per hour
Step-by-step explanation:
72 pages = 3 hours
To find the rate of pages per hour, divide both sides by 3.
72/3 = 24, 3/3=1
