Answer:
60% more.
Step-by-step explanation:
So you know 50 divided by 2 is 25, so add that to 50 to get 75. then you need to add ten more so you divide 50 by 5. so then 25+5 is 30 and 30 is 60% of 50 so it is marked up by 60% more.

Answer: Answer is x= 7 1/2
Step-by-step explanation:
This will be positive since there is no negative signs.
Answer:
x = 7 1/2
Step-by-step explanation:
12x = 90 Times both sides by 5
x = 90/12 Divide by 12 on both sides
x = 7 6/12 Find the closest multiplier
x = 7 1/2 Simplify
B. What is the balance after 2 years.
Answer:
A. $24
B. $224
Step-by-step explanation:
For simple interest, the formula is I = PRT where I = interest earned, P = principal amount borrowed/deposited, R = rate as a decimal, and T = time in years.
I = (200)(0.06)(2)
I = 24
Then add that to the amount deposited ($200) and you're done.
200 + 24 = $224
