Answer: (a) 8 (b) 12
Step-by-step explanation:
Given : The number of different kinds of soups = 6
The number of different kinds of salad = 2
(a) If you are having either soup or salad, then the total number of choices you have :-

Hence, the total number of choices you have = 8
(b) If you are having both soup and salad, then the number of choices you have :-

Hence, the total number of choices you have = 12
7b + 3 - 4b = 3 - 3(b + 4)
3b + 3 = 3 - 3b - 12
3b + 3b = 3 - 12 - 3 = -12
6b = -12
b = -12/6 = -2
b = -2
This is an expression if she only gets pedicure
y = 35
If she wants to get massage, multiply the cost for a minute with the number of minutes.
Find cost per minute first
cost = 50/20
cost = 2.5
So the expression would be
y = 35 + 2.5x
y = 2.5x + 35
