Answer:
The original price of the shoes was $90.
Step-by-step explanation:
25% off means the price Joe paid for it is 75% of the original price.
Set up an equation:
75/100 = 67.50/x
Cross multiply
75 × x = 100 × 67.50
75x = 6750
x = 90
Check our work:
First solve for 25% off of 90 (our answer).
25% = 0.25
90 × 0.25 = 22.50
Next, subtract the discount from 90.
90 - 22.50 = 67.50
67.50 was what Joe paid so this is correct.
Answer:
Option C is correct.
Step-by-step explanation:
The given data would be most appropriately displayed by a box-and-whisker plot.
a box-and-whisker plot will represent it by representing in form of rectangle with second and third quartile
And in box and whisker plot
The vertical line will represent the median.
Therefore, option C is correct.
360 miles in 4 hours. Find the rate by dividing 360 by 4.
360/4=90MPH
90MPH * 10hrs = 900 miles.
estimate: 0.8
actual: 0.74285714285
x + 77 + 47 + 2x + x = 360
4x = 236
You answer: x = 59
59+77+59+47+59+59=360
