Answer:
200 pencils and 120 pens
Step-by-step explanation:
Let the number of pencils be x while pens be y.
Considering the cost of whole purchase then, we get the equation
0.5x+y=220
Considering the number of items bought, then the equation is
x-y=80
Adding the two equations then we have
1.5x=300
x=300/1.5=200
Consideeing that x-y=80 and x is 200 then
200-y=80
y=200-80=120
Therefore, the pencils were 200 and pens 120 pieces
Roger: $24
Bethan: $36
Explanation:
4/5 of $75 is $60
So $60 is distributed to Roger and Bethan in the ratio 2 : 3.
Add the numbers in the ratio 2 : 3
2 + 3 = 5
Divide $60 by 5
60 ÷ 5 = 12
Multiply each number in the ratio 2 : 3 by 12:
2 • 12 : 3 • 12
= 24 : 36
