Daniela goes shopping during a sale. She finds out that the store has 40 percent off on shoes and 20 percent off dresses. If Daniela buys 2 pairs of shoes originally priced at $50 a pair and a dress originally priced at $100, how much money does she spend?
Let’s work this out in a step by step way to be sure we have the right answer.
140
Two pairs of shoes at $50 a pair costs $50 x 2 = $100.

The shoes are discounted by 40 percent so she only pays 100 - 40 = 60 percent of the original price.

Therefore the two pairs of shoes cost $100 x 0.

60 = $60.

The dress is discounted by 20 percent so she only pays 100 - 20 = 80 percent of the original price.

Therefore the dress costs $100 x 0.

80 = $80.

In total Daniela spends $60 + $80 = $140 for two pairs of shoes and a dress.

The final answer: 140
