Answer:
Mr K purchased 6 chicken sandwiches and 6 pizza slices.
Step-by-step explanation:
Let Mr. K purchased number of chicken sandwiches = x
and number of pizza slices = y
Since total number of dancers = 12
then the equation will be
x + y = 12 --------(1)
Mr K. spent total amount = $72
Therefore, equation to purchase x sandwiches, y pizza slices and 12 drinks will be
6x + 3y + 1.5×(12) = 72
6x + 3y + 18 = 72
6x + 3y = 54
2x + y = 18 -------(2)
We subtract equation (1) from (2)
(2x + y) - (x + y) = 18 - 12
x = 6
from equation (1)
6 + y = 12
y = 6
Therefore, Mr K purchase 6 chicken sandwiches, 6 pizza slices.
Answer:
40 pens
Step-by-step explanation:
Let the total number of pens Ron had be x.
We need to find the fraction of the pen that were blue.
3/8 of them were black and 1/4 of them were red. This means that the fraction of the pens that were blue is:
1 - (3/8 + 1/4) = 1 - 5/8 = 3/8
There were 15 blue pens. This means that 3/8 of x is 15:
3/8 * x = 15
x = 15 * 8/3 = 40 pens
Ron had 40 pens.
