Answer:

  $125

Step-by-step explanation:

With a 20% off coupon, the price you pay is 80% of the marked price. If that amount is $100, you have ...

  $100 = 0.80p

  p = $100/0.80 = $125

The maximum price of the shoes you can buy is $125.

_____

<em>Check</em>

20% of $125 is -.20×$125 = $25. When that is subtracted, the price you pay is ...

  $125 -25 = $100

Answer:

$125

Step-by-step explanation:

let the maximum price be 'x'

x -( \frac{20}{100} \times x) = 100

x - ( \frac{x}{5} ) = 100

\frac{4x}{5}  = 100

4x = 500

x = 125

A stadium already has 250 people in it at noon.If 35 people per minute enter the stadium,how many are in the stadium at 1:30 p.M
Talja [164]
12:00 to 1:30 , that is 90 minutes
if 35 people enter each minute then it should be multiplied by the number of minutes
that being said, 90 x 35 = 3,150 people are in the stadium at 1:30
