Let x = roller coaster ticket
let y = boat ride ticket
x + y = 10
4x + 3y = 37
x = 10 - y
4x + 3y = 37
4(10-y) + 3y = 37
40 - 4y + 3y = 37
-y = 37 - 40
-y = -3
y = -3/-1
y = 3
x = 10 - y
x = 10 - 3
x = 7
x = 7 ; y = 3
4x + 3y = 37
4(7) + 3(3) = 37
28 + 9 = 37
37 = 37

Step-by-step explanation:
interest=p*t*r/100
=x*5*8/100*2
=40x/200
=x/5
so to find principal use formula
amount=principal +interest
5454=x+x/5
5454=5x+x/5
5454*5=6x
27270/6=x
4545=x
therefore ,sum of money(principal)=rupees.4545
Hope this helps u!!
