Brainliest is given to the correct answer.

Answer 1

Answer:

Joni.

Step-by-step explanation:

Joni's calculation is the closest to the actual value.

How much Wally was off: $12.8-12.546=0.254$

How much Rex was off: $12.8-12.59=0.21$

How much Amanda was off: $12.8-12.69=0.11$

How much Joni was off: $12.8-12.75=0.05$

She was off by 0.05, which is the smallest out of the other people.

This means that her calculation was the closest to the actual value of 12.8 oz.

Thus, her calculation is the most accurate.
