Movie tickets are $4 for regular admission and $3 for seniors. On a night where there were 190 people and total sales of $720 how many regular admission tickets were sold? A. 50
B. 150
C. 40
D. 140

150

Step-by-step explanation:

So if we rearrange the second equation we can get:

s = 190 - a

Now we substitute this into the first equation:

4a + 3(190 - a) = 720

4a + (570 - 3a) = 720

4a + 570 - 3a = 720

4a - 3a = 720 - 570

a = 150

good luck on your studies! : )
