Answer:
14
Step-by-step explanation:
This can be solved by writing 2 equations and solving simultaneously.
Let <em><u>number of Adult tickets be A, and number of child tickets be C.</u></em>
<em><u /></em>
<u><em>"Bob bought 24 hockey tickets":</em></u>
<em><u>"Adult tickets cost $5.50, and child tickets cost $2.00...Bob bought 24 hockey tickets for $83":</u></em>
Now we can solve the first equation for A and substitute in 2nd equation and get the value of C.
A + C = 24
A = 24 - C
Now,
5.5 A + 2 C = 83
5.5 (24 - C) + 2C = 83
132 - 5.5C + 2C = 83
-3.5 C = 83 - 132
-3.5C = - 49
C = 14
Hence, Bob bought 14 child tickets
Answer:
The unit rate of change is of
Step-by-step explanation:
We are given a set of points (x,y).
To find the unit rate of change, we take two points, and divide the change in y by the change in x.
Points (4,9) and (8,12)
Change in y: 12 - 9 = 3
Change in x: 8 - 4 = 4
Unit rate of change:
