Jessica_Moore 3 years ago 1. Tony and Belinda have a combined age of 56. Belinda is 8 more than twice Tony’s age. How old is each? (2 points) 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? (2 points) 3. Your piggy bank has a total of 46 coins in it; some are dimes and some are quarters. If you have a total of \$7.00, how many quarters and how many dimes do you have? (2 points) help!!

For number one, you need to take the combined age and subtract 8 and then divide by 2.

Once you divide by two you add the 8 back to one of the 2 numbers and thats belinda age.

take tony's age = x belinda's age = 2x+8 combined age = 56 solve for x u get tony's age and do 2x+8 u get belinda's

If you take the equation 30*.10 you get 3 then add 16*.25 you get 7. 7 is the total amount the money adds up to and there is exactly 46 dimes and quarters used.

Thats for number 3.
