Answer:
-40% change
Step-by-step explanation:
- This change is a decrease, so first you need to find the difference between the two numbers--> 125 - 75 = 50
- Next, you divide by the original number, so 50 ÷ 125 = 0.4
- Finally, you multiply your answer by 100, so 0.4 x 100 = 40%. Because this is a decreasing change, you add a negative sign.
FULL EXPLANATION & ANSWER:
Replace a and b in the equation with their values given:
-0.5(7(-6)-12(-10)-(8.4(-10)-14(-6))
Multiply within the parentheses
-0.5(-42 + 120) -(-84 + 84)
Add inside the parenthesis:
-0.5(78)-0
Multiply:
-.05 x 78 = -39
The answer is -39
