Solución
1. Calculate the cost of walnuts:
\[
\text{Cost of walnuts} = 2 \, \text{kg} \times \$6.32/\text{kg} = \$12.64.
\]
2. Calculate the cost of almonds:
\[
\text{Cost of almonds} = 3 \, \text{kg} \times \$7.09/\text{kg} = \$21.27.
\]
3. Find the total cost:
\[
\text{Total cost} = \$12.64 + \$21.27 = \$33.91.
\]
4. Calculate the change from a \$100 bill:
\[
\text{Change} = \$100 - \$33.91 = \$66.09.
\]
Julia should get back \(\$66.09\) in change.

To find out how much Julia spent in total, we calculate the cost of the walnuts and the almonds separately and then add them together. For the walnuts: \[ 2 \text{ kg} \times 6.32 \text{ USD/kg} = 12.64 \text{ USD} \] For the almonds: \[ 3 \text{ kg} \times 7.09 \text{ USD/kg} = 21.27 \text{ USD} \] Adding these costs together: \[ 12.64 \text{ USD} + 21.27 \text{ USD} = 33.91 \text{ USD} \] Now, subtracting this total from the amount given to the cashier: \[ 100 \text{ USD} - 33.91 \text{ USD} = 66.09 \text{ USD} \] Julia should get back **$66.09** in change.
