Find the total cost of the cappuccinos by multiplying the price by the quantity: 3 cappuccinos x $2/cappuccino = $<<3*2=6>>6
Then do the same for the iced teas: 2 iced teas x $3/tea = $<<2*3=6>>6
Then do the same for the cafe lattes: 2 lattes x $1.5/latte = $<<2*1.5=3>>3
Then do the same for the espressos: 2 espressos x $1 = $<<2*1=2>>2
In total Sandy pays $6 + $6 + $3 + $2 = $<<6+6+3+2=17>>17
Sandy will receive $20 - $17 = $<<20-17=3>>3 in change
