<span>Let x = # of $1 bill, y = # of $5 bill, z = # of $10 bill, then there're 3 functions you can get:
(1). x + 5y + 10z = 96
</span><span>(2). x +1 = y + z
</span><span>(3). x + y + z =23
From (1), (2), get 6y + 11z = 97 (4)
From (2), (3), get 2y + 2z = 24 (5)
From (4), (5), get y = 7, z =5, plug these into (2) get x = 11</span>

If master chief has three and a half cookies, and the arbiter has five and three quarters of a cookie, how many cookies do they
nikklg [1K]

Answer:

9\dfrac{1}{4}

4\dfrac{5}{8}

Step-by-step explanation:

The master chief has three and a half cookies i.e. 3\dfrac{1}{2} = \dfrac{7}{2} numbers of cookies.

Again the arbiter has five and three quarters of a cookie i.e. 5\dfrac{3}{4} = \dfrac{23}{4} number of cookies.

Therefore, in total there are (\dfrac{7}{2} +\dfrac{23}{4} ) = \dfrac{37}{4} = 9\dfrac{1}{4} numbers of cookies.

If we divide the total number of cookies in to equal parts and distribute to then then each of them will get \dfrac{37}{4 \times 2} = \dfrac{37}{8} = 4\dfrac{5}{8} numbers of cookies. (Answer)
