To find how much Jacob spent, we can simplify the expression $4.75 + ($2.43 + $1.25) using the Commutative and Associative Properties.
First, let's apply the Commutative Property of Addition. According to this property, the order of the numbers being added does not affect the sum. So, we can rearrange the numbers within the parentheses:
$4.75 + ($2.43 + $1.25) can be rewritten as $4.75 + ($1.25 + $2.43).
Next, let's apply the Associative Property of Addition. According to this property, the grouping of numbers being added does not affect the sum. So, we can change the order of addition within the parentheses:
$4.75 + ($1.25 + $2.43) can be rewritten as $4.75 + $1.25 + $2.43.
Now, let's simplify the expression by adding the numbers:
$4.75 + $1.25 + $2.43 = $8.43.
Therefore, Jacob spent $8.43 in total.
