Answer:
(a) C = 25r (b) 8 rooms (c) 7 rooms
Step-by-step explanation:
MARK ME BRAINLIEST PLEASE!!!!!!!!
(a) C=25r
(b) C = 25r
200 = 25r,
200/25 = 25r/25
200/25 = 8
8 = r, therefore 8 rooms can be cleaned for $200
(c) 200-25 = 25r
200-25=175, so 175 = 25r, then divide both sides by 25, and you get
7 = r , so therefore 7 rooms can be cleaned for $200

Answer:
There is 55% probability that I order both the sandwich and soup
Step-by-step explanation:
P(sandwich) = 0.8
P(Soup) = 0.7
P(neither sandwich nor soup) = 0.05
P(sandwich or soup) = 1 - P(neither sandwich nor soup)
P(sandwich or soup) = 1 - 0.05 = 0.95
P(Sandwich & Soup) = x
P(Sandwich only) = 0.8 - x
P(Soup only) = 0.7 - x
P(sandwich or soup) = P(Sandwich only) + P(Soup only) + P(Sandwich & Soup)
Note that P(neither sandwich nor soup) has already been used to get the P(sandwich or soup) and should not be included in the above formula. Don't make that mistake!
0.95 = 0.8 - x + 0.7 - x + x
0.95 = 1.50 - x
x = 1.50 - 0.95
x = 0.55
There is 55% probability that I order both the sandwich and soup
