Lorenzo has 4 packages of granola bars. Each package has 10 bars.
He eats one bar from each package.

Which equation shows how Lorenzo can correctly find the total number of granola bars remaining?

4 × 10 – 4 = 36 granola bars

4 × 10 × 1 = 40 granola bars

4 × 10 + 4 = 44 granola bars

4 + 10 – 4 = 10 granola bars
