This math problem has got me stumped: 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?
Can you show me the way?
1 kilo of apples costs $4.
2 kilos of bananas costs 2 * 2 = $4.
2 kilos of oranges costs 2 * 3 = $6.
She pays 4 + 4 + 6= $14 in total.
