Answer:
Step-by-step explanation:
Part A
Cost = T - (15/100) * T
Cost = (85/100)*T
Part B
You are asked to take 15% off the cost of something. The first equation is very clear how to do that -- just take 15% of T away from T
The second part is not so obvious if you are not familiar with it, but the result will be the same.
Start with the first equation
Cost = T - (15/100) T Change 1 T to 100 / 100
Cost = 100*T/100T - 15/100T
Cost = 85 /100 * T
Part C
Cost = Phone - 14 at Top quality. Red in Graph below
Cost = 75/100 * Phone at Big value. Blue in Graph belos
The graph below is a good way to answer this. I won't solve it algebraically when the graph will give you a much better idea which phone to get.
Answer: Up to a phone cost of 55 dollars, the red phone is the better buy.
After 55$ the blue phone is better.
Try this with a couple of values for phone,
Answer: 70
Step-by-step explanation: 6300/90=70 Brainliest please?
(4*100,000,000) + (5*1,000) + (2*1)
A) fifth = 5/5 (this is a fraction) 1/5 is 1 fifth of 1. Get what i'm saying? So then the will be <u>5 fifths in a whole
</u>
B) ok turn 2 1/3 into a improper fraction and that will be <u>7/3</u>
C) ok so 4 (a whole number) is 20/5 so you divide 20/5 with 2/5 (ignore this if you don't know what i'm talking about this is in middle school) so that will = <u>10</u>
Answer:
franchise fast-food restaurant located in the Northeast specializing in halfpound hamburgers, fish sandwiches, and chicken sandwiches. Soft drinks and French fries are
also available. The planning department of Bun-and-Run Inc. reports that the distribution of
daily sales for restaurants follows the normal distribution and that the population standard
deviation is $3,000. A sample of 40 showed the mean daily sales to be $20,000. Find the 95%
confidence interval for the population mean.
