Answer 2

The entry in
`a_(32)` is 6.3.

Explanation:

The table shows the prices of three items in a deli. The deli offers a 10% discount on weekends.

In a matrix
`a_(mn)` represents the nth element of mth row.

It is given that matrix A shows the discounted weekend rates. So the entry in
`a_(32)` represents the discounted prize of pizza with extra cheese.

The original price of pizza with extra cheese is $7. After discount of 10%, the price of pizza with extra cheese is

`7-7* (10)/(100)=7-0.7=6.3`

The discounted prize of pizza with extra cheese is $6.3.

Therefore the entry in
`a_(32)` is 6.3.
