Answer: 9) 15m-30
11.) 5b-5
Step-by-step explanation:
With Distributive Property, you are basically looking at the question like this: (5*3)m +(5*-6)
When you take a negative and multiply it with a positive it will be a negative number.
it would then get simplified as
15m-30
Same with number 11. look at it as
(5*1)b +(5*-1)
again a negative and a positive gets you a negative so your answer would be
5b-5

Step-by-step explanation:
Hi there!
Shop 1.
12 pens equals $9.00
1 pen equals $9.00 / 12 = $0.75
120 pens equals $0.75 × 120 = $90.00
Shop 2.
10 pens equals $7.80
1 pen equals $7.80 / 10 = $0.78
120 pens equals $0.78 × 120 = $93.60
Therefore shop 1 is the cheapest shop and offers the best deal. When buying 120 pens the second shop is $3.60 more expensive.
