Answer : The weight of the package of flour that she left is, 0.84 pounds.
Step-by-step explanation :
As we are given that the Victoria has a 2 pound package of flour.
First we have to calculate the amount of flour use to make a pizza.
Amount of use to make a pizza = [tex]\frac{2}{5}\times 2\text{ pounds}=\frac{4}{5}\text{ pounds}[/tex]
Now we have to calculate the amount of flour use to make a bread.
She then uses 3/10 of the remaining flour to make bread. That means,
Remaining flour to make bread = [tex]1-\frac{2}{5}=\frac{3}{5}[/tex]
Fraction of flour use to make a bread = [tex]\frac{3}{10}\times \frac{3}{5}[/tex]
Amount of use to make a bread = [tex]\frac{3}{10}\times \frac{3}{5}\times 2\text{ pounds}=\frac{9}{25}\text{ pounds}[/tex]
Now we have to calculate the weight of the package of flour that she has left.
Weight of the package of flour that she has left = Total amount of flour - (Sum of flour use to make a pizza and bread)
Weight of the package of flour that she has left = [tex]2-(\frac{4}{5}+\frac{9}{25})[/tex] pounds
Weight of the package of flour that she has left = [tex]2-\frac{4}{5}-\frac{9}{25}[/tex] pounds
Weight of the package of flour that she has left = [tex]\frac{21}{25}[/tex] pounds
Weight of the package of flour that she has left = 0.84 pounds
Thus, the weight of the package of flour that she left is, 0.84 pounds.
