cost of pencil = x = 0.07
and cost of eraser = y = 0.03
Step-by-step explanation:
let cost of pencil = x
and cost of eraser = y
So, we have equations:
Solving both equations to find value of x and y
Let:
Multiply eq(1) with 4 and eq(2) with 3 and subtract
Putting value of x in equation 1:
So, x= 0.07 and y = 0.03
cost of pencil = x = 0.07
and cost of eraser = y = 0.03

Answer:
26.2 points
Step-by-step explanation:
To find the average, find their total number of points and divide by the number of games
total points/number of games
To find their total points, add all their points together
35+31+31+10+24=131
Then, divide by the number of games (5)
131/5=26.2
So, they scored an average of 26.2 points
Hope this helps! :)
