Any number larger than 36 would be a counter examples.

When n is equal to 36, both sides of the inequality are equal to 216. As you get larger than 36 the right side is larger than the left side. Therefore, the inequality is not true.

Which expression is NOT equivalent to 125.78 ÷ 1.23?

Viefleur [7K]

Answer:

Choice C.

Step-by-step explanation:

For an expression to be equivalent you need to multiply or divide the 2 numbers in the original expression by the same number.

For example A is equivalent because both 125.78 and 1.23 have been multiplied by 100.

The odd one out is C because 125.78 has been divided by 100 but 1.23 has been multiplied by 10.

Answer:

Price = $4.50

Maximum revenue = $2,430

Step-by-step explanation:

The concession stand sells 600 bags of peanut at $4.00 (600, $4.00).

If there is a $1 increase in price, the number of bags old will decrease by 120, which mens that 480 bags of peanuts will be sold at $5.00 (480, $5.00).

Tracing a linear relationship between price and quantity sold with the two given points:

$m = \frac{5-4}{480-600}\\ m=-\frac{1}{120}$
