If the question is asking how many bags of ice cream she delivered on Wednesday, the answer would be 1. To solve the equation, you would start by calculating how many bags of ice cream she sold on Tuesday. To do this would would multiply how many bags she sold (17) by the weight of each bag (4.53 kilograms) this equation would look like 17 x 4.53 kilo = 77.01 kilo. You would then subtract it from the goal she sold on both days (80.42). This equation would look like 80.42 - 77.01 = 4.53. Meaning she sold 1 bag on Wednesday! I hope this helps!
