Scientific notation The table shows the amount of money raised by each region the four regions used a total of $ (5.38×10^4) How much money did the West Raise?

Answer 1

9514 1404 393

Answer:

  $8.65×10^3

Step-by-step explanation:

The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.

  West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4

  = (5.38 -1.46 -2.38 -0.675)×10^4

  = 0.865×10^4 = 8.65×10^3

West raised $8.65×10^3.
