A publishing house is selling subscriptions to its magazines for 20% off the original price. If a subscription to Newsweek Magazine is on sale for $72, how much does it usually cost?

90

Step-by-step explanation:

The magazines are sold at a discount. Discount reduces the price of the good

If the magazines are sold at 20%, the magazine's price would be 80% (100% - 20%) of the original price

let a represent price of the magazine before the discount

This equation represents price of the magazine after the discount

0.8 x a = $72

Divide both sides by 0.8 and find a

a = $90

2 x t divided by n

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
