cost $6 each and shipping was $4. The expression 6n +4
represents the total cost for n books ordered. How much
did Mr. Taft's order cost?

Answer 1

the order cosr was $120

Answer 2

Mr. Taft's order cost is equal to $\ 128$

An algebraic expression is an expression obtained by a finite number of the fundamental operations of algebra upon symbols representing numbers.

Total cost for $n$ books $=6n+4$

Cost of each book $=\ 6$

Cost of shipping $=\ 4$

So,

Total cost of $20$ books $=6(20)+4$

                                     $=\ 124$

Total order cost $=$ Total cost of $20$ books $+$ Cost of shipping

                           $=\ 124+\ 4$

                           $=\ 128$
