1. pedro had $14.90 in his wallet. he spent $1.25 on a drink. how much does he have left?
(a) estimate the answer by rounding to the nearest whole numbers before subtracting.
(b) will your estimate be high or low? explain.
(c) find the difference. show your work.

(a) 14.90 rounded is 15, and 1.25 rounded is 1, so 15-1 is $14.
(b) My estimation will be high because I had to round up on the larger number and round down on the smaller number leaving a larger gap between the answer and the estimation.
(c) 14.90-1.25=13.65, so Pedro has $13.65 left in his wallet. But the difference between the estimation and the answer is 14-13.65=0.35 so its a $0.35 difference between the estimation and the answer for how much would be left in Pedro's wallet.
