Answer:
440 Rock CDs
Step-by-step explanation:
Let number of rock CDs be "r", and
number of Jazz CDs be "j"
4 times as many Rock as Jazz, so we can write:
r = 4j
Total of 550 CDs, thus we can write equation 2:
r + j = 550
Now we replace 2nd equation with 1st equation and find j first:
r + j = 550
4j + j = 550
5j = 550
j = 550/5
j = 110
Now, finding r:
r = 4j
r = 4(110)
r = 440
There are 110 Jazz CDs and 440 Rock CDs
Answer:
Number of Model A press = 9 and Number of Model B press = 5
Step-by-step explanation:
Number of books Model A can print per day = 70
Number of books Model B can print per day = 55
Let x be the number of Model A press and y be that of Model B press.
Total number of printing presses = 14
x + y = 14 ----------------1
Total number of books printed per day = 905
70x + 55y = 905-------2
Putting y = 14 - x in equation 2, we get:
70x + 55(14 - x) = 905
15x = 135
x = 9
y = 14 - 9 = 5
Hence number of Model A press is 9 and that of Model B press is 5.
