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?
Thoughts? Step-by-step reasoning:
The total cost for the flour is 3 x $3 = $9. The total cost of the tray of eggs is 3 x $10 = $30. The total cost for the liter of milk is 7 x $5 = $35. The total cost for the box of baking soda is 2 x $3 = $6. Therefore, the total cost for all the ingredients is $9 + $30 + $35 + $6 = $80.
Thus, the answer is 80.
