To find the total cost of buying 1 1/2 pounds of almonds and 2 1/2 pounds of cashews using the expression 9.99d + 12.99c, we substitute d = 1 1/2 and c = 2 1/2 into the expression and calculate the result.
First, convert 1 1/2 to a decimal: 1 1/2 = 1.5
Then, convert 2 1/2 to a decimal: 2 1/2 = 2.5
Substituting the values into the expression:
9.99(1.5) + 12.99(2.5)
Calculating:
14.985 + 32.475
The total cost to buy 1 1/2 pounds of almonds and 2 1/2 pounds of cashews is $47.46.

The variable w goes next to the $25.50 instead of the $217 because the variable w represents the number of weeks. In this scenario, Misumi is depositing $25.50 into her bank account every week, so the amount she has deposited after w weeks would be $25.50 multiplied by the number of weeks, which is w.
On the other hand, the $217 is the initial amount that Misumi starts with in her bank account. It does not change over time and is not dependent on the number of weeks. Therefore, it remains constant and does not need to be multiplied by any variable.
