Answer: The probability that the sum is less 7 or less is 20/51.
First, we start by selecting an ace because the question says one card is an ace. Therefore, our final probability is out of 51.
Our goal is to have 7 or less. That means we can draw a 2, 3, 4, 5, or 6. Since, there are 4 of each type, we have 4 x 5 = 20 different possibilities.

Answer:
16 hours
Step-by-step explanation:
company A $800 plus $16 per hour
company B $720 plus $21 per hour
im going to start with 10 and go from there
company A
16 x 10 = 160
800 + 160 = 960
company B
21 x 10 = 210
720 + 210 = 930
it needs to go up so lets try 15
company A
16 x 15 = 240
800 + 240 = 1040
company B
21 x 15 = 315
720 + 315 = 1035
one more maybe 16
company A
16 x 16 = 256
800 + 256 = 1056
company B
21 x 16 = 336
720 + 336 = 10 56
I think it’s increase of 4%
Part A:The original brand was 12$ each and the new one is 8$ each.
12-8=4
Part B:she will save 16$ each month because y=12*4 and y=8*4 is 16$
