Butter Crate Snacks sends a selection of treats in the mail each month. Sidney bought a 4 . month subscription for a friend. She used a one-time coupon and received \( \$ 8 \) off the total cost. Sidney paid \( \$ 40 \) in all. How much does each month normally cost?

Let \( x \) be the normal monthly cost of the subscription. Since Sidney bought a 4-month subscription, the total normal cost before applying the coupon would be: \[ 4x \] Sidney used a one-time coupon that gave her \( \$ 8 \) off the total cost, so the equation for the total cost she paid is: \[ 4x - 8 = 40 \] Now, we can solve for \( x \): 1. Add \( 8 \) to both sides of the equation: \[ 4x = 40 + 8 \] \[ 4x = 48 \] 2. Divide both sides by \( 4 \): \[ x = \frac{48}{4} \] \[ x = 12 \] Thus, the normal cost for each month is \( \boxed{12} \) dollars.
