At the school store, Isla buys sandwich for $5.80, taco for $2.09, and comic book for $1.84 and pays with $20.00. Which is the BEST estimate method to check the change?
A
Round the first item only and do $20.00 − $6.00.
B
Round each price up to the next dollar, then do $20.00 − $11.00 ≈ $9.00.
C
Round each price down to the lower dollar, then do $20.00 − $8.00 ≈ $12.00.
D
Round each price to the nearest dollar, add to estimate the total, then do $20.00 − $10.00 ≈ $10.00.
