Written in Python:

The bakery shop sells $3$ types of pies.

Apple pies cost $$3$ each

Cherry pies cost $$4$ each

Peach pies cost $$2$ each

And this is how many they sold in $4$ days:

For example, the value of sales for Monday is calculated this way:

Apple pie value $+$ Cherry pie value $+$ Peach pie value

$$3$xx$13+$$$4$xx$8+$$$2$xx$6=$$$83$

And for Tuesday: $$39+$ $$47+$ $$24=$ $$63$

And for Wednesday: $$3$xx$7+$$$4$xx$4+$$$2$xx$0=$$$37$

And for Thursday: $$3$xx$15+$$$4$xx$6+$$$2$xx$3=$$$75$

You need to have two lists:

one one$-$dimensional and

Define matrix price as a one$-$dimensional array

price $=[3,4,2]$ # one$-$dimensional list, unit in $ for Apple, Cherry, and

Peach pie

one two$-$dimensional

Define matrix pie $(3$x$4),$ each column represents a day, Monday$-$Thursday

pie $=[$

$[13,9,7,15],$ # $1$st row for Apple

$[8,7,4,6],$ # $2$nd row for Cherry

$[6,4,0,3]$ # $3$rd row for Peach

$]$

As shown above, you may call the one$-$dimensional list price and the two$-$dimensional list pie.

The final result$/$output can be in a form list such as

$[83,63,37,75]$

Or

Mon Tue Wed Thu

$$83$ $$63$ $$37$ $$75$
