Answer 2

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)
SOLUTION: Let tony age = t years, Bel age = 56 - t years
56 - t = 2t + 8
56 - 8 = 2t + t ==> 3t = 48 ==> t = 16 years
THUS Tony = 16 years, and Belinda = 40 years <=====> ANSWER

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)
SOLUTION:
Let adults = a, and Students = 150 - a
NOW, 45a + 28.5(150 - a) = 4770
45a + 4275 - 28.5a = 4770 ==> 16.5a = 4770 - 4275 = 495
a = 495 / 16.5 = 30, THUS,
Adult = 30, STUDENTS = 120 <=============> ANSWER

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)
LET, Dimes = d, and Quarter = 46 - d
d/10 + (46 - d) /4 = 7
Multiply both sides by 20, we get,
2d + 5(46 - d) = 140 ==> 2d + 230 - 5d = 140
-3d = 140 - 230 = -90 ==> d = 30
THUS, Dimes = 30, and Quarters = 16 <==============> ANSWER
