The 7th graders at Wilson Middle School are taking a field trip to the science museum. So far, 12 students have turned in a total of $81 to pay for their ticket.
What is the constant of proportionality equation for this problem?
If all 72 students turn in their ticket money, how much money would be collected?
Group of answer choices
y = 1/12(x) $6.75 would be collected
y = 12(x) $840.00 would be collected
y = 6.75(x) $486.00 would be collected
y = 81(x) $5832.00 would be collected
