A running store offers a 15% discount on
Rudik [331]

Answer:

The cost of each pair of shoes before the discount=$67.65

Step-by-step explanation:

Step 1

Use the expression below to determine original cost of the 2 pairs of shoes as follows;

A=O-R

where;

A=total bill after discount

O=original cost of 2 pairs of shoe

R=discount amount

In our case;

A=$110.50

O=unknown=x

R=15% of O=(15/100)×x=0.15 x

replacing;

115=x-0.15 x

115=0.85 x

x=115/0.85

x=135.294

Original cost of the 2 pairs of shoes=$135.294

Original cost of a pair of shoes=135.294/2=$67.65

The cost of each pair of shoes before the discount=$67.65

PLEASE HELP!!!! A boat can travel at an average speed of 10 miles per hour in still water. Traveling with the current, it can tr
Soloha48 [4]

Answer:

  • 2 mph

Step-by-step explanation:

Let the speed of current be x

<u>Speed of the boat in same direction as current is</u>

  • 10 + x

<u>Speed against the current is</u>

  • 10 - x

<u>Based on the given we get the equation for time</u>

  • 6/(10 + x) = 4/(10 - x)

<u>Solving for x</u>

  • 6(10 - x) = 4(10 + x)
  • 60 - 6x = 40 + 4x
  • 6x + 4x = 60 - 40
  • 10x = 20
  • x = 2

The answer is 2 mph
