Answer:
Step-by-step explanation:
A. k/5 = 3: Isolate k by multiplying both sides of this equation by 5:
k = 15
B. 3.5d = 70; Divide both sides by 3.5, obtaining d = 20
C. 4 1/2 = 1 1/2n; Rewrite 4 1/2 and 1 1/2 as improper fractions:
9/2 = (3/2)n. Now multiply both sides by (2/3): 3 = n
The minimum cost option can be obtained simply by multiplying the number of ordered printers by the cost of one printer and adding the costs of both types of printers. Considering the options:
69 x 237 + 51 x 122 = 22,575
40 x 237 + 80 x 122 = 19,240
51 x 237 + 69 x 122 = 20,505
80 x 237 + 40 x 122 = 23,840
Therefore, the lowest cost option is to buy 40 of printer A and 80 of printer B
The equation, x + 2y ≤ 1600 is satisfied only by options:
x = 400; y = 600
x = 1600
Substituting these into the profit equation:
14(400) + 22(600) - 900 = 17,900
14(1600) + 22(0) - 900 = 21,500
Therefore, the option (1,600 , 0) will produce greatest profit.
44/35 in simplest form is 1 9/35.
Hope this helps!
