Janelle buys 13 cases of water. Each case contains 16 bottles. Then she drinks 6 bottles of water. Veronica creates a numerical expression to represent the situation. Her expression, (16 - 13) x 6, has a mistake.

( 13*16) - 6

Step-by-step explanation:

there are 13 cases containing 16 bottles.

janelle has drank 6 bottles of water

the formula she created was (16 - 13) x 6

the error is that 6 needs to be deducted from the total bottles

and the cases needs to be multiplied by the bottles

= ( 13*16) - 6

the corrected expression is : ( 13*16) - 6
