How many positive factors of 200 are divisible by 4?

Stella [2.4K]

Answer:

C. 6, D. 20, B. 18, B. 9

Step-by-step explanation:

#1. Factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100 & 200, of which 6 are divisible by 4 (4, 8, 20, 40, 100 & 200)

#2. Prime factors of 35 are 7 & 5, twice the sum of these factors, k = 24. k-4 = 20

#3. Non-multiples of 4 nor 5 between 16 and 45 are 17, 18, 19, 21, 22, 23, 26, 27, 29, 31, 33, 34, 37, 38, 39, 41, 42 & 43...thus 18 non-multiples

#4. Even factors of 120 greater than 1 and less than 40 are 2, 4, 6, 8, 10, 12, 20, 24 & 30...thus there are 9 even factors

The owner of a music store received a shipment of stereos at a cost of $160 each. What will the selling price be if he applies a

kumpel [21]

The selling price will be $232 if he applies a 45% markup.

Step-by-step explanation:

Cost of each stereo = $160

Mark up = 45%

Amount of mark up = $\frac{45}{100}*160$

Amount of mark up = $\frac{7200}{100} = \$72$

Selling price = Cost of stereo + mark up

Selling price = 160 + 72 = $232

The selling price will be $232 if he applies a 45% markup.
