Question

1.     
The
food charges in a hostel are as follows: 


For the first day, the charges are Rs.100 and
for the subsequent days it is Rs 50 per day. Taking the number of days as x and
total charges as Rs y, write a linear equation for this information

Answer 1

y = x*50+100
we just need to add 100 to the multiplication of days and price per day to get the total price.

Answer 2

y=50x+50

Step-by-step explanation:

for first day =100

total days =x

then

for x-1 days = 50 (x-1)

=50x-50

y =50x-50+100

y=50x+50
