Can you please help me with this problem

$1.15

Step-by-step explanation:

add the cost of all of the items: 1 + 3.50 + 3.50 + 1 = 9

multiply 9 by the given discount: 9 x 0.15 = 1.35

you get 1.15, this is the dollar price of the discount

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.
