Answer:
c) 2 + 3 = 5 TRUE
d) 2 + (–3) = -1 True
Step-by-step explanation:
When adding integers (positive and negative whole numbers), there are three cases:
- Positive and positive increases and sum is positive. Ex. 4 + 6 = 10
- Positive and negative where you subtract and take the sign of the larger number. Ex. 3 + -8 = -5 or -3 + 8 = 5
- Negative and negative decrease and the sum if negative. Ex. -4 + -6 = -10.
Use these rules to simplify each expression.
a) 2 + (–3) = -1 not 1 FALSE
b) –3 + 2 = -1 not 5 FALSE
c) 2 + 3 = 5 TRUE
d) 2 + (–3) = -1 True

Answer:
The correct answer is A) $105
Step-by-step explanation:
In this real-world problem, the cost to groom both dogs is (the puppy) + (the adult dog) = x.
For the first step, y = 40, if x <= 25.
y = 50, if 25 < x < 50.
if x >= 50, then y = 0.50x + 25
So therefore, substitute the puppy + adult dog = x
25 + 80 = x
105 = x
So, the final answer is $105.
