In order to know which number is closest to 27. 8 x 9.6, we must first get the product between the two numbers. So, 27.8 x 9.6 is equal to 266.88. To round this off, we get 267. Among the given choices, the number that is closest to 267 is only 280. Therefore, the correct answer would be option A.

Hence, option B is correct.

<h3>What is the recursive rule?</h3>

A rule is defined such that its definition includes itself.

Example:

F(x) = F(x-1) + c

is one such recursive rule.

Hareem takes medicine to control his blood pressure.

he takes a 25 mg pill in the morning.

Suppose that 60% of the medicine is processed by hareem's body by the time he takes a second 25 mg pill in the evening.

So, the recursive definition for the amount of the blood pressure medicine in hareem bloodstream after n hours would be;

a_1=25, a_n = 0.60_{n-1} +25

Hence, option B is correct.
