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?
Two pairs of shoes at $50 a pair costs $50 x 2 = $

<output>100</output>
100.
The shoes are discounted by 40 percent so she only pays 100 - 40 = 
<gadget id="calculator">100-40</gadget>
<output>60</output>
60 percent of the original price.
Therefore the two pairs of shoes cost $100 x 0.60 = $
<gadget id="calculator">100*0.60</gadget>
<output>60</output>
60.
The dress is discounted by 20 percent so she only pays 100 - 20 = 
<gadget id="calculator">100-20</gadget>
<output>80</output>
80 percent of the original price.
Therefore the dress costs $100 x 0.80 = $
<gadget id="calculator">100*0.80</gadget>
<output>80</output>
80.
In total Daniela spends $60 + $80 = $
<gadget id="calculator">60+80</gadget>
<output>140</output>
140 for two pairs of shoes and a dress.
