the cost of the project is 'y' in which he uses one hour and 30 minutes of internet and prints 'x' pages. Express the relationship between x and y.
​

Answer 1

y = 15 + 5x

Step-by-step explanation:

If the cyber cafe charges Rs. 10 for computer usage for 1 hour, then for 1 hour and 30 minutes i.e. 1.5 hours the cafe will charge (10 × 1.5) = 15 Rs.

Now, the print cost for x pages at the rate of Rs. 5 per page will be Rs. 5x.

If the total project cost is Rs. y then we can write the equation that expresses the relation between x and y is

y = 15 + 5x (Answer)
