Which expression represents the product of 3 and (5/4n + 1.8)?

A) 5.55n

B) 9.15n

C) 3.75n + 1.8

D) 3.75n + 5.4

Option D

$\text{The product of 3 and } (5)/(4)n + 1.8 \text{ is } 3.75n + 5.4$

Given that we have to find product of 3 and
(5)/(4)n + 1.8

Product means multiplication

Hence we have to multiply 3 and
(5)/(4)n + 1.8

Product is given as:

$\rightarrow 3 * ((5)/(4)n + 1.8)$

Multiply 3 with terms inside the bracket

$\rightarrow 3 * (5)/(4)n+ 3 * 1.8$

Simplify the above expression by reducing to lowest terms

$\rightarrow (15n)/(4) + 5.4$

Express in decimal form

$\rightarrow (15n)/(4) + 5.4 = 3.75n + 5.4$

Thus option D is correct
