<human>:  A baker bought cooking ingredients in the supermarket. She bought 3 boxes of flour that cost $3 each box, 3 trays of eggs that cost $10 for each tray, 7 liters of milk that cost $5 each liter, and 2 boxes of baking soda that cost $3 each box. How much will she have to pay for everything?
<bot>: How much did the flour cost? ** The total cost for the flour is 3 x $3 = $<<3*3=9>>9.
How much did the eggs cost? ** The total cost of the tray of eggs is 3 x $10 = $<<3*10=30>>30.
How much did the milk cost? ** The total cost for the liter of milk is 7 x $5 = $<<7*5=35>>35.
How much did the baking soda cost? ** The total cost for the box of baking soda is 2 x $3 = $<<2*3=6>>6.
How much did the ingredients cost? ** Therefore, the total cost for all the ingredients is $9 + $30 + $35 + $6 = $<<9+30+35+6=80>>80.
