Need help Please I have to have this turned in NOW!!!!
1.Tony and Belinda have a combined age of 56. Belinda is 8 more than twice Tony’s age. How old is each?
I like comparison. In both equations, solve for y=. It's already done for you in the second. Then set the two equations equal to each other, eliminating the y and solve for x.
2.Salisbury High School decided to take their students on a field trip to a theme park. A total of 150 people went on the trip. Adults pay $45.00 for a ticket and students pay $28.50 for a ticket. How many students and how many adults went to the park if they paid a total of $4770?
Okay here the variables (x and y) are the number of adults and the number of students. So we can say
x = number of adults
y = number of students
These are the 2 statements:
1. A total of 150 people went on the trip
2. they paid a total of $4770
Can you turn these into equations?
Sorry was afk for a sec. Yes that's correct. Now use substitution to solve. Solve for x or y in the first equation and plug it into the second equation
Let's solve for y in the first equation
x+y = 150
y= 150-x
Now plug it into the second
45x + 28.5y = 4770
45x + 28.5(150-x) = 4770
now expand and solve for x
