Answer:
96 inches in 8 ft
Step-by-step explanation:
The number of inches is 12 times the number of feet. (Each foot is 12 inches.)
_____
<em>Additional comment</em>
The number of inches is proportional to the number of feet, so the number of inches in 8 feet will be half the number of inches in 16 feet. You may find it easier to divide the table value 192 inches by 2 than to multiply 8 feet by 12.
Answer:
a) x + y ≤ 16
y/x ≥ 3/5
12*x + 4*y ≥ 72
b) see picture attached
c) 5 pizza makers and 3 cashiers should be hired.
Step-by-step explanation:
a) Let's define:
x: amount of pizza maker
y: amount of cashier
From conditions in the question:
x + y ≤ 16
y/x ≥ 3/5
12*x + 4*y ≥ 72
b) In the picture attached, the feasible region (also called solution region) is shown.
c) We want to minimize:
10*x + 6*y
subject to the previous restrictions.
It is known that the optimum solution is on the vertex of the feasible region (it is a linear system). Evaluating cost function at each point, we get:
10*1 + 6*15 = 100
10*5 + 6*3 = 68
10*10 + 6*6 = 136
Then, 5 pizza makers and 3 cashiers should be hired.
