Hilton university drama club sold 311 tickets for a play. student tickets cost 50 cents each, nonstudent tickets cost $1.50. if total receipts were 385.50, find how many tickets of each type were sold

X= number of student tickets

Y= number of on student tickets

x+y=311

0.50x + 1.50y = 385.50

Solve x in 1st equation

X+y=311

X= -y + 311

Now substitute x into second equation to solve for y

0.50(-y+311)+ 1.50y = 385.50

-0.50y+311.50+1.50y=385.50

Y+311.50=385.50

Y= 385.50-311.50

Y= 74

Now substitute y answer to first equation to find x

X+y=311

X+ 74=311

X= 311-74

X= 237

So 237 students tickets and 74 non students tickets

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

definitely a. the others have almost all data points on one side of the line.
