Answer:
There are 21 twenties and 8 fifties in the drawer.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of twenties
y is the number of fifties.
A cash drawer contains 29 bills.
This means that x + y = 29.
The total value of the bills is $820.
This means that 20x + 50y = 820.
So
x + y = 29
20x + 50y = 820
From the first equation, x = 29 - y. So:
20x + 50y = 820
20(29 - y) + 50y = 820
580 - 20y + 50y = 820
30y = 240
y = 8
And
x = 29 - y = 29 - 8 = 21
There are 21 twenties and 8 fifties.
Answer:
She used 6.825 pints of withe paint to paint her bedroom walls
Step-by-step explanation:
We know Cathy used 9.1 pints of paint and 1/4 is blue.
first we have to calculate the white paint, we are going to calculate it by subtracting 1/4 of the total paint
1 - 1/4 = 4/4 - 1/4 = 3/4
Now that we know that 3/4 of the total paint is white, we have to multiply it by the amount of paint so we get how many pints of paint are white
3/4 * 9.1 = 6.825
She used 6.825 pints of withe paint to paint her bedroom walls
