Barbra bought 2 greetings cards at $1.50 each, 3 packages of wrapping paper at $2.29 each and 1 roll of ribbon for $1.45. How much did she spend altogether?

$11.32

Step-by-step explanation:

Greeting Cards = $1.5 x 2 = $3

Wrapping Paper = $2.29 x 3 =  $6.87

Ribbon = $1.45 x 1 = $1.45

So now we must add the totals to figure out how much money Barbra spent in total.

$3 + $6.87 + $1.45 = $11.32

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
