I'm pretty sure he saved $27. I just divided 90 by 20 to get the amount of times he would have saved 6 dollars. Then, I multiplied that number, 4.5, times 6 to get the amount he saved. Hope that helps (and that it's correct lol). <span />
Answer:
C. 28 = (2x - 1)(x)
Step-by-step explanation:
Given :
There is a rectangular swimming pool.
Width of swimming pool is x
Length is one less than twice the width
Area of the swimming pool is 28 sq ft.
To Find : Equation could be used to model the area of the swimming pool.
Solution:
Since we are given that Length is one less than twice the width.
And width is x (given)
So, length = 2x-1
Area of the swimming pool is 28 sq ft.
Now ,
Formula of area of rectangle : Length*Width
⇒28= (2x-1)(x)
So, equation used to model the area of the swimming pool: 28= (2x-1)(x)
Hence Option c is correct.
Answer:
Option C
Step-by-step explanation:
The monthly payment is £114.
Step-by-step explanation:
Step 1:
First, we determine how much the TV costs in total.
The TV is priced at £1,200 and a 20% VAT.
The total cost of the TV
So the total cost of the TV is £1,440.
If a deposit of £300 is paid, the balance to be paid
This £1,140 is to be paid in the next 10 months.
Step 2:
To calculate the monthly cost to be paid we divide the total cost by the number of months.
The cost to be paid every month
So the monthly payment is £114.
