A concert charges $30 admission and $15 per shirt. Alyssa paid $75 at the concert for her admission and shirts. Write and solve an equation to find the number of shirts Alyssa bought. Explain what your variable represents.

75-30/15=x

Step-by-step explanation:

75-30=45

45/15=3

75-30/15=x

30+15(x)=75               so x would =3

Step-by-step explanation:

So you have one ticket which is $30, then you add 15 times however many shirts she buys which in total will equal $75. She would have bought 3 shirts. So 30+ 15(3)=75. Hope that helps!
