Question

Estimation Gabe goes to the mall. If k is the number of items he bought, the exp11.02k +21 gives the amount he spent in dollars at one store. Then he spent 30 dollars at anotherstore. Find the expression which represents the amount Gabo spent at the mall. Then estimatehow much Gabe spent if he bought 2 items.What expression represents the amount in dollars that Gabe spent at the mall?

Answer 1

The expression 11.02k+21 indicates how much did Gabe spend in the first store he visited.

In the second store, he spent 30 dollars.

To determine how much he spent in the mall you have to add the amounts he spent in both stores:

$\begin{gathered} \text{Store}1+\text{Store}2 \\ (11.02k+21)+30 \\ 11.02k+21+30 \\ 11.02k+51 \end{gathered}$

The expression that represents his total expenses at the mall is

$11.02k+51$

"k" represents the number of items he bought. If he bought k=2 items, you can calculate how much he spent at the mall as follows:

$\begin{gathered} 11.02k+51 \\ 11.02\cdot2+51 \\ 72.04 \end{gathered}$

Gabe spent an estimate of 72.04 dollars at the mall
