I solved this via trial & error, not much to say, other than all other combinations of seven coins did not total to $0.61, so here you go.
1 quarter ($0.25)
2 dimes ($0.20)
3 nickels ($0.15)
1 penny ($0.01)

The annual county being held for 5 and 1/2 days is just extra info you dont to know. Just use the rest of the info already given. It says the ride needs to make 1000 "at least" so put 1000 on the right side of the equal sign.And now it says the operator has to pay safety inspection and the ride rental fee so add $65 with $200. So you need to now put the variable p somewhere in the equation. It gives you that each person has to pay 6 dollars. so you can put 6p in the equation. (sorry if all this sounds wierd but its easier to explain face to face) Now in the final equation your left with "6p+265=1000". so now you just move everything to the right side and leave the p behind and you have the equation for p :)
I think it is a mixed number sorry if I’m wrong
The sum of 170 and 130 is 300. Simply add the addends and you'll get the sum.
1st statement
Justin has 7.5 more than Eva 7.5+E
Eva = E
2nd statement
Emma has 12 less than Justin J - 12
when J= Justin = 7.5 + E
last statement
Eva+Justin+Emma = 63
E + (7.5+E) + (7.5+E-12) =63
ADD UP
3E + 15 - 12 = 63
3E + 3 = 63
3E=63 - 3
3E=60
E=20 EMMA receives 20
J=7.5+20
J=27.5 JUSTIN receives 27.5
M=J-12
M=27.5-12
M=15.5 EMMA receives 15.5
