So basically, the first question after the word problem is asking you to write an equation to represent the value of Mama's car after a certain amount of years (t). Since the value of her car decreases by 3% each year, you could multiply 3% by the original value of her car, to find what 3% is, OR you could subtract 19,400 (the value of her car after 1 year) from 20,000 INSTEAD of multiplying 20,000 by 3%.
Equation: value=20,000 - 600t
To answer the next question, just plug it into the equation you created.
500<20,000 - 600t
-19500< -600t
32.5>t
Final Answer: It would take at least 32 and 1/2 years for the value of Mama's car to be less than $500.
Hope this helps!! :)
Answer:
14(y + 2).
Step-by-step explanation:
32 +2/3(21y - 6)
Distributing the 2/3 over the parentheses:
= 32 + 2/3*21y + 2/3 * -6
= 32 + 14y - 4
= 14y + 28
= 14(y + 2).
-2+4-3+8-2-0.5 = -7.5+12
-7.5+12 = 4.5
4.5/6 (number of months) = 0.75
0.75 = -3/4
-3/4 is your answer. :)
It's D. That is the only true statement.
20,000 = 80% of the original price so 20,000 divided by 80 = 250 then multiply that by 100 equals 250000 which is the original price
hope this helps !
