Which equations could model this problem? four friends purchased tickets to a play. the total cost for all four tickets was $186. what was the unit price, t, per ticket? choose all answers that are correct.

It's 4t = 186.

Multiply the number of friends to the unit cost of the ticket to arrive at the number 186.
Since there are four friends, multiply four to the unit cost per ticket 4 * t to have the total 186.

4t = 186 is the correct model equation based on the above word problem.

However, to find the unit cost per ticket divide 186 by 4.

4t/4 = 186/4
t = 46.50

to check: substitute t by 46.50
4(46.50) = 186
186 = 186
