Answer: The common ratio, r
Step-by-step explanation: r^2 = 1536/24... r^2 = 64... Square root both sides to get... r = 8
7th term - 4th term = 3
31 - 16 = 15.... 15/3 = 5... so d = 5
Let the price of a notebook = X.
Multiply the cost of a notebook by the quantity, so you get 3x.
Add that to the price of a calculator to get the total spent:
60.54 = 45.87 + 3x
Now solve for x:
Subtract the cost of the calculator from both sides:
3x = 14.67
Divide both sides by 3:
x = 14.67 / 3
x = 4.89
A notebook cost $4.89
