<human>:  The price of buying a wooden toy at the new Craftee And Best store is $20, and the cost of buying a hat is $10. If Kendra went to the shop with a $100 bill and bought two wooden toys and three hats, calculate the change she received.
<bot>: How much did Kendra pay for the toys? ** When Kendra bought 2 toys, she paid 2*$20 = $<<2*20=40>>40
How much did Kendra pay for the hats? ** Since the price of a hat is $10, when Kendra bought 3 hats, she paid 3*$10 = $<<3*10=30>>30
How much did Kendra spend? ** The total costs for the hats and wooden toys Kendra bought is $40+$30 = $<<40+30=70>>70
How much change did Kendra receive? ** From the $100 bill, Kendra received change worth $100-$70 =$<<100-70=30>>30
