Answer:
Number of erasers bought = 122
Number of markers bought = 700
Step-by-step explanation:
Given that:
Two items to be bought:
1. Eraser for the dry board
2. Maker
Total items bought = 822
Total money spent = $953
Cost of each eraser = $1.50
Cost of each marker = $1.10
Let the number of erasers bought = [tex]x[/tex]
Let the number of markers bought = [tex]y[/tex]
As per question statement:
[tex]x+y=822 ..... (1)[/tex]
[tex]1.50x+1.10y=953\\\Rightarrow 15x+11y=9530 ..... (2)[/tex]
Multiplying equation (1) with 11 and subtracting from equation (2):
[tex]4x = 9530 - 822\times 11\\\Rightarrow 4x = 488\\\Rightarrow x=122[/tex]
By equation (1):
[tex]\Rightarrow y =822-122\\\Rightarrow y = 700[/tex]
Therefore, the answer is:
Number of erasers bought = 122
Number of markers bought = 700
