Answer:
A: Spent = 12c + 7b + 24
B: 93 dollars
Step-by-step explanation:
Cost = 12*c + 7*b + 24
If c = 4 and b = 3 then the total cost is
Cost = 12*4 + 7*3 + 24 Substitute and combine factors
Cost = 48 + 21 + 24 Combine Terms
Cost = 93 dollars Answer
Let x= hours spent job A
let y= hours spent job B
14x + 12.50y = 600
x + y = 45
x=-y +45
14(-y+45) + 12.5y = 600
-14y + 630 + 12.5
-1.5x + 630 = 600
-1.5x=-30
x=20
(20) + y = 45
y= 25
20 hours job A, 25 hours job B
Inequalities are used to represent unequal expressions.
The inequality is: (c) ![\mathbf{3p + 6 \ge 18}](https://tex.z-dn.net/?f=%5Cmathbf%7B3p%20%2B%206%20%5Cge%2018%7D)
The given parameter is:
![\mathbf{Free = 6}](https://tex.z-dn.net/?f=%5Cmathbf%7BFree%20%3D%206%7D)
Represent the number of 3-point field goals with p.
So, the total number of points is:
![\mathbf{Total = 3 \times p + Free}](https://tex.z-dn.net/?f=%5Cmathbf%7BTotal%20%3D%203%20%5Ctimes%20p%20%2B%20Free%7D)
![\mathbf{Total = 3 p + Free}](https://tex.z-dn.net/?f=%5Cmathbf%7BTotal%20%3D%203%20p%20%2B%20Free%7D)
Substitute 6 for Free
![\mathbf{Total = 3 p + 6}](https://tex.z-dn.net/?f=%5Cmathbf%7BTotal%20%3D%203%20p%20%2B%206%7D)
He scored no fewer than 18 points, means that:
He scored 18 or more points
So, the inequality is:
![\mathbf{Total = 3 p + 6 \ge 18}](https://tex.z-dn.net/?f=%5Cmathbf%7BTotal%20%3D%203%20p%20%2B%206%20%5Cge%2018%7D)
Rewrite as:
![\mathbf{3p + 6 \ge 18}](https://tex.z-dn.net/?f=%5Cmathbf%7B3p%20%2B%206%20%5Cge%2018%7D)
Hence, the correct option is (c)
