Robert and Teddy are planning to buy snacks for their friends. Robert orders five boxes of pizza at $10 each box and ten cans of soft drinks at $2 each. Teddy buys six hamburgers at $3 each and an additional ten cans of soft drinks. How much do they spend in all? Let's think first. Chain of thought:
Five boxes of pizza cost 5 x $10 = $50. Ten cans of soft drinks cost 10 x $2 = $20. So, Robert spends $50 + $20 = $70. Six hamburgers cost 6 x $3 = $18. Thus, Teddy spends $18 + $20 = $38. Therefore, they spend $70 + $38 = $108 in all.
Therefore, the answer is 106.
