Answer:
C. 
Step-by-step explanation:
Given that A and B are matrices and
is a scalar, then the distributive property of scalar multiplication over addition is given by;

The distributive property of scalar multiplication over subtraction is

The correct answer is C.
Total discount for 10 group tickets = 10 · 0.05t
Amount of discount per ticket = 0.05t
Number of tickets = 10
Cost of buying 10 single tickets = 10t
Solution:
Cost for single ticket = t dollars
Discount percent per ticket = 5%
Number of tickets bought = 10
Total discount for 10 group tickets = Number of tickets × Discount amount
= 10 × 0.05t
Total discount for 10 group tickets = 10 · 0.05t
Amount of discount per ticket = 5%t
=
t
= 0.05t
Amount of discount per ticket = 0.05t
Number of tickets = 10
Cost of buying 10 single tickets = 10t
Question A
take $100.80 divide it by 35 which would equal 2.88
so round that up for 3.0 for the closest answer
Question B
take 49.2 and divide it by 6 which would equal 8.2
so round it to the nearest number which would be 8.0
Question C
take 0.78 and divide it by 20L which would equal 0.039
so round that up to the closest number which would be 0.04L
Answer: C. 11/15
Step-by-step explanation:
Given : The fraction of stores inventory is children's clothing=
The fraction of stores inventory is women's clothing=
Since both events are independent.
Therefore, the fraction of the total inventory is children's or women's clothing = (Fraction of stores inventory is children's clothing ) + (Fraction of stores inventory is women's clothing )


∴ The fraction of the total inventory is children's or women's clothing 
Hence, the correct answer is C. 11/15 .
