Answer:

Calculus texts: 600
History texts: 0
Marketing texts: 0

Step-by-step explanation:

Each Calculus text returns $10/2 = $5 per unit of shelf space. For History and Marketing texts, the respective numbers are $4/1 = $4 per unit, and $8/4 = $2 per unit. Using 1200 units of shelf space for 600 Calculus texts returns ...

$5/unit × 1200 units = $6000 . . . profit

Any other use of units of shelf space will reduce profit.

A number is selected randomly from the integer from 10to30 what is the probability of picking a multiple of 4or5

arlik [135]

Answer:

$\frac{3}{7}$

Step-by-step explanation:

Start by finding how many integers there are from 10-30...

30-10+1=20+1=21

Note we have to add 1 since it is inclusive.

Now, let's find how many multiples of 4 or 5 there are from 10-30...

4*3=12

4*4=16

4*5=20

4*6=24

4*7=28

5*2=10

5*3=15

5*4=20

5*5=25

5*6=30

5+5-1=9

Note we have to subtract 1 since 20 is counted twice.

The probability would be...

$\frac{Multiples\ of\ four\ and\ five\ from\ 10-30}{Amount\ of\ integers\ between\ 10-30}=\frac{9}{21}=\frac{3}{7}$

Joe ate 1/3 of a pizza and jane ate 1/5 of the pizza. How much of the pizza was eaten

NikAS [45]

Answer:

7/15

Step-by-step explanation:

If we're seeing how much pizza they both ate, we would add them together.

$\frac{1}{3}+\frac{1}{5}$

Find the common denominator

$\frac{5}{15}+ \frac{3}{15}$

add

$\frac{7}{15}$

7/15 of the pizza was eaten
