Question

a. the change over the next 6 years
select the correct answer below.
a. 6(30) = 180
b. −6(−30) = 180
c. −6(30) = −180
d. 6(−30) = −180

Explanation:

Step1: Analyze the context (change over 6 years)

Assume a negative change per year (e.g., decrease of 30 per year). So the number of years is 6, and the change per year is -30.

Step2: Calculate the total change

Total change = number of years × change per year = \( 6\times(-30) \).
Calculate \( 6\times(-30) = -180 \).

Step3: Match with options

Option D is \( 6(-30) = -180 \), which matches the calculation.

Answer:

D. \( 6(-30) = -180 \)
