Julie had $20.00 in her pocket. She spent $7.40. About what percent of her money does she still have?
posledela

63%


First, we have to take 20.00 - 7.40 which gets us 12.60.


Then, we use the formula where we put the 12.60 on top of a fraction bar, and the 20.00 on bottom.

We do 12.60 x 100 which makes 1260.


Lastly, we divide that by the 20.00 which gets us 63.


So, Julie has 63% of her money left.


I hope this helped!!!

5. Adam drives his car with an average velocity of 85 km/h eastward. How long will it take him to drive
NISA [10]

Answer:

x = 6.59 hrs = about 6 hours, 35 minutes

Step-by-step explanation:

Adam drives at 85 km / h. Let's set up equivalent fractions to see how long if he drives 560 km.

\frac{85 km}{1  hr} = \frac{560 km}{x hr}

Cross-multiply:

85x = 560

Solve for x:

560/85 = x

<u>x = 6.59 hrs = about 6 hours, 35 minutes</u>
