question: Catherine goes to the grocery store. She buys 1 kilo of apples for $4, 2 kilos of bananas for $2 per kilo, and 2 kilos of oranges for $3 per kilo. How many dollars does she pay in total?
answer: 1 kilo of apples costs $<<1*4=4>>4.
  2 kilos of bananas costs 2 * 2 = $<<2*2=4>>4.
  2 kilos of oranges costs 2 * 3 = $<<2*3=6>>6.
  She pays 4 + 4 + 6= $<<4+4+6=14>>14 in total.
