Question 1

Method 1: 4 1/2 = (4.2)+1 over 2. And that equals 8+1 over 2. To get a total of 9/2 ft^2.  Then we take the 13/1 students and multiply by the 9/2 and end up with 13 x9 over 2x1 solving that equation to get a fraction of 117/2 ft^2.

Method 2:  For the second method we start with 4 1/2 = (4 + 1/2) then we multiply 13 (4 + 1/2) now we have (13 x 4) + (13 x 1/2) which equals to (52) + (13/2) Now we can convert 13/2 is the same as 6.5 or 6 1/2 so now we just add 52 + (13/2) to get 58 1/2 ft^2 as the answer.

58 1/2 ft^2

Question 2

A) 15(2/5) = 30/5 = $ 6.00

40(1/3) = 40/3 = $13.33333 repeated or we can change that by rounding to get $13.33

10(3/4) = 30/4 = $7.50

B)

$ 6.00

$13.33

$7.50

6.00 + 13.33 + 7.50 = $26.83

Question 3

A.

Juan Increase 25/350 = .071 * 100 = 7 %

Rhia Increase 75/275 = .273 * 100 = 27 %

Max Decrease 40/400 = .1 * 100 = 10 %

b.

Juan sold more than $355 but his increase was less than 10% so he did not get a bonus.

Rhia had an increase more than 10% but she did not sell more than $355 so she did not get a bonus.

Max had a decrease so he did not get a bonus.


Hope this helps! Have a great day! :D
