Answer:
Correct choices are 1 and 4
Step-by-step explanation:
As per data given we have:
- Median temperature is 75°F and 88°F
- And the range from the median is 5° for both cities
This gives us lowest temperatures of:
- 75° -5° = 70° and 88° - 5°= 83° respectively
And high temperatures are:
- 75° + 5° = 80° and 88° + 5° = 93°
<u>Answer choices based on above details:</u>
- Choice 1 - correct
- Choice 2 - incorrect. Correct answer is 93°
- Choice 3 - incorrect. Correct answer is 93° - 70° = 23°
- Choice 4 - correct
Answer:
$64.32
Step-by-step explanation:
What you do is:
$53.60×20% → $53.60×0.2
$53.60×0.2=$10.72
$10.72 is the amount of money taken off because of the sale.
Then what you do is:
$53.60+$10.72=_____
53.60
<u>+10.72</u>
64.32
The original price was $64.32.
