Answer:

original price = $30.00

Step-by-step explanation:

note that the original price is 100% , then

1% = $1.50 ÷ 5 = $0.30 , so

Answer:

$30

  • if 5% of an item = $1.50
  • then 100% of the item = ?

let the original price = x

\frac{5}{100}  =  \frac{1.5}{x}

5x = 100 \times 1.5

5x = 150

therefore

x = $30

so the original price is $30

Dafna11 [192]

Answer:

The annual interest rate  compounded quarterly = 4.5%

Time period = 8 years

Now from compound Interest method for quarterly .

Amount = Principal ( 1 + \frac{Rate}{4 \times 100})^{4 \times Time}

Or,Amount = $6,000 ( 1 + \frac{4.5}{4 \times 100})^{4 \times 8}

Or, Amount = $6,000 (1.430)

alicia got 60 questions correct on her science test. if she received a score of 75% how many questions were on the test?
Tomtit [17]
If we know that she got 75%, we can write it as the fraction 75/100.
We also know that she got 60 correct out of an unknown number of questions, which we can call 'x'
We means we know that 75/100 = 60/x (the number of questions)
Cross multiply to get an equation.
75 * x=60 * 100 -----> 75x=6000
Divide both sides by 75 to solve for x.
6000/75=80
x=80, meaning that her test had 80 questions on it.

The equation y= 39 4x describes the number of miles y that an airplane travels in x minutes. What is the constant speed of the a
7nadin3 [17]
Speed: distance traveled in a given time

y=distance ( given in miles).
x = time (given in minutes)

Speed = y/x

y = 39.4x

By rearranging this y/x =39.4 ( is the constant speed). don’t forget this is mile/minutes

There are 4 x 60 minutes in 4 hours

Hence, you are asked the distance (y) in 240 min

y = 39.4x
y = 39.4 miles/minutes x (240) minutes

y = 9456 miles
