plz give right ans. only​

Answer 1

Step-by-step explanation:

let fixed tution fee for a month be X

additional charge for a day be y

Sonia paid tution fee including late fee for 10 days. X+10y

A/q

X+10y =2150. eqn(1)

Sofia paid tution fee including late fee for 7 days =X+7y

A/q

X+7y= 2105. (eqn 2)

subtract eqn 2 from 1

X+ 10y-x-7y = 2150 -2105

3y=45

y = 15

put value y in eqn 1

X+ 10 *15 =2150

X= 2150 -150

X=2000

monthly fee of tution =X=2000

late fee for per day = y = 15
