Final answer:
To round to the nearest tenth in cents, look at the digit in the hundredth place. If it's 5 or greater, round up. If it's less than 5, round down. Option C, $2.30, would round to $2.30.
Step-by-step explanation:
To round to the nearest tenth in cents, we look at the hundredth place of the dollar amount. If the digit in the hundredth place is 5 or greater, we round up to the next tenth. If the digit is less than 5, we round down to the current tenth.
A. $2.20 would round to $2.20 because the digit in the hundredth place is 0, which is less than 5.
B. $2.10 would round to $2.10 because the digit in the hundredth place is 0, which is less than 5.
C. $2.30 would round to $2.30 because the digit in the hundredth place is 3, which is 5 or greater.
D. $2.40 would round to $2.40 because the digit in the hundredth place is 4, which is 5 or greater.
