Can someone please answer this question I need it today please answer it correctly and please show work

answer:

Question 1

Part A:  Write an expression

2.25 + 5k = 9.00

Part B:  What is the price for each key/solve for k

2.25 + 5k = 9.00

2.25 + 5k - 2.25 = 9.00 - 2.25

5k / 5 = 6.75 / 5

k = 1.35 per each key

Questions 2

Part A:  Write an inequality

45 + 10b < 65

Part B:  What is the price for each bottle/solve for b

45 + 10b < 65

45 - 45 + 10b < 65 - 45

10b / 10 < 20 / 10

b < 2 for each bottle

Part C:  Graph the solution

Make a bubble that is not filled in at 2, and make a line go from that to the left side.  

10b is the number of bottles of water, plus the 45 you already spent and this has to be less than 65

10b + 45 < 65

10b < 65 - 45

10b < 20

b < 2

so the most amount of money you can spend on the water is less than 2 dollars, so 1.99

on the number line, you'll have to write out numbers and at 2, draw an empty circle above it and a line going backwards

hope i helped!
