Answer 1

To find the total cost for Mrs. McDonald to purchase 10 canisters of coffee and 8 boxes of tea, we will use the expression \( 7c + 4b \) where \( c \) is the number of canisters of coffee and \( b \) is the number of boxes of tea.

Given:

• \( c = 10 \) (canisters of coffee)
• \( b = 8 \) (boxes of tea)

Now we can substitute these values into the equation:

\[ 7c + 4b = 7(10) + 4(8) \]

Calculating each term:

\[ = 70 + 32 \] \[ = 102 \]

Therefore, the total cost for Mrs. McDonald to purchase 10 canisters of coffee and 8 boxes of tea is $102.

The correct response is:

$102
