The answer is:
The pineapples Mr. Lester sells are $2.40
In order to calculate the total cost of the purchase, we must first assess that there were two items bought, turkey and lamb. Next, we see multiply the cost of the first item by its quantity, so:
cost(T) = 2.15 * 7.89
cost(T) = $16.96
And repeat for the second item:
cost(L) = 1.87 * 7.89
cost (L) = $14.75
Finally, the total cost is the sum of these costs. So
Total = 16.96 + 14.75
Total = $31.71
Option C:
is equivalent to the given expression.
Solution:
Given expression:

To find which expression is equivalent to the given expression.

Using exponent rule: 


Using exponent rule: 


Divide both numerator and denominator by the common factor –6.


Therefore,
is equivalent to the given expression.
Hence Option C is the correct answer.
Let's say

is the measure of the first angle and

is measure of the supplement of

. We know that supplementary angles add up to 180°, so

. We also know that

. Therefore,

. It follows that

, therefore, the first angle is 174° and the second angle is 6°.
19) Notice that:

Therefore, the nth term has the form:
