Question

bob bought lunch at school. he had a sandwich and a dessert that cost him $8. his dessert cost $2.25. solve the equation 8 = s + 2.25 to find the cost of bobs sandwich, s. s = \square ; bobs sandwich cost $\square. (type whole numbers or decimals.)

Explanation:

Step1: Subtract 2.25 from both sides

To solve for \( s \) in the equation \( 8 = s + 2.25 \), we subtract 2.25 from both sides. This gives us \( 8 - 2.25 = s + 2.25 - 2.25 \).

Step2: Calculate the result

Simplifying the left side, \( 8 - 2.25 = 5.75 \), and the right side simplifies to \( s \) (since \( 2.25 - 2.25 = 0 \)). So \( s = 5.75 \).

Answer:

\( s = 5.75 \); Bob's sandwich cost \$5.75.
