Answer:
$183
Step-by-step explanation:
He buys 25 calculators for $41 each meaning he spends $1025 in total. He was able to sell 22 calculators for $50 which amounts to $1,100. He then returns and is refunded for the original price of the 3 calculators meaning he gets $123 dollars back but he also has to pay $5 for each calculator he returned which takes away $15 from his profit. $123-$15= $108. ($1,100+$108)-$1025=$183.
Answer: Relative error = 50%
Step-by-step explanation:
Relative error Re = Absolute error/True value × 100%
True value = 2 scoops
Measured(used) value = 3 scoops
Absolute error Ae = measured(used) value - True value
= 3 scoops - 2 scoops
Ae = 1 scoop
Re = 1/2 × 100%
Re = 50%
The graph has to be a straight line that pass through the origin (0,0)
Answer:
Step-by-step explanation:
P = 3,000
r = 5% = 0.05
t = 9 years
Amount after 9 years is
A = P (1+ r)^t
A = 3,000(1+ 0.05)^9 = 3,000 * 1.05^9 = 4653.984648 ≈ $4,653.98
The balance after 9 years, rounded to the nearest cent is
$4,653 and 98 cents
