The formula [tex]F(C)=\frac{9}{5} C+32[/tex] calculates the temperature in degrees Fahrenheit, given a temperature in degrees Celsius.
You can find an equation for the temperature in degrees Celsius for a given temperature in degrees Fahrenheit by finding the function's
Answer (3)
$2.75x > $9.35
$9.35/$2.75=3.4 lbs.
Drew can buy 3 lbs of seedless grapes for less than $9.35.
Inequality: x = the number of pounds of grapes
2.75x < 9.35 [2.75x is less than 9.35, since Drew must spend less than $9.35]
Solution:
To find the solution, you need to isolate/get "x" by itself in the inequality.
2.75x < 9.35 Divide 2.75 on both sides to get "x" by itself
2.75 2.75 x < 2.75 9.35
x < 3.4
Interpretation:
x is less than 3.4, so Drew has to buy less than 3.4 pounds of grapes in order to spend less than 9.35 [ w hi c hi s t h e m os t / ma x im u m he has]
Drew can purchase fewer than 3.4 pounds of grapes to spend less than $9.35. This means he could buy up to 3 pounds or slightly more, but not 3.4 pounds. For example, buying 3 pounds would cost him $8.25, which is under his spending limit.
