Question

Tamika sells magazines door to door. On her first day, she sells 12 magazines. She intends to sell 5 additional magazines each day. If she meets her goal, how many magazines will she have sold in 27 days

Answer 1

we have the following:

`\begin{gathered} a_1=12 \\ a_n=a_1+d\cdot n \\ a_(10)=12+5\cdot n=12+135 \\ a_(10)=147 \end{gathered}`

therefore, the answer is 147 magazines
