Admission to the zoo is $6 for children and $9 for adults. On a certain day, 1480 people go to the zoo and $10,500 is collected. How many children and how many adults went to the zoo? i dont want the awanser but how do i go about solveing this

OpenStudy (fibonaccichick666):

ok so, you need to set up 2 equations.

OpenStudy (fibonaccichick666):

say the number of children=x and adults=y, does that help?

OpenStudy (anonymous):

well yes i know that but i the problem is that im setting it up as x+y=1480 y= then i get stuck

OpenStudy (fibonaccichick666):

well wait,

OpenStudy (fibonaccichick666):

first eq perfect, exactly what you need

OpenStudy (fibonaccichick666):

for the second I'll give you half, .....=10500

OpenStudy (anonymous):

so would it be y6+x9=10500

OpenStudy (fibonaccichick666):

so close, what did y represent?

OpenStudy (anonymous):

children and x adults

OpenStudy (fibonaccichick666):

you flipped them which is fine, but make sure you define x and y

OpenStudy (fibonaccichick666):

like in writing on your paper

OpenStudy (anonymous):

ok thx

OpenStudy (fibonaccichick666):

then we usually put the number we know first, just a style thing, but since multiplication is commutative, they are equivalent

OpenStudy (fibonaccichick666):
