Answer:
price of pencil is 0.74 and eraser is 0.72$
Step-by-step explanation:
Let, "p" represent pencils
and "e" represents erasers.
hence, according to question
13p+10e=16.75 ________(1)
and 25p+2e=19.85________(2)
Multiplying equation (2) by 5,
hence, 125p+10e=99.25________(3)
Substracting equation (3) and (1)
125p+10e-(13p+10e)=99.25-16.75
hence, 112p=82.5
p=0.74
substituting the value in equation (1),
13(0.74)+10e=16.75
9.57+10e=16.75
on solving,
e=0.72
hence, price of one pencil is 0.75$, and price of one eraser is $0.72
