Final answer:
Mr. Alvarado has $26.39 after he buys the pants and shirt and returns the hat.
Step-by-step explanation:
To find out how much money Mr. Alvarado has after he buys the pants and shirt and returns the hat, we need to subtract the cost of the pants and shirt and add back the amount he received from returning the hat. Let's calculate:
Mr. Alvarado's initial amount of money is $70.
He buys a pair of pants for $33.76, so he now has $70 - $33.76 = $36.24.
He buys a shirt for $29.52, so he now has $36.24 - $29.52 = $6.72.
He returns a hat he bought for $19.67, so he now has $6.72 + $19.67 = $26.39.
Therefore, Mr. Alvarado has $26.39 after he buys the pants and shirt and returns the hat.
