Question
Answer:
Same exact thing as last time Bright! Devin has to multiply 28.99 by 0.30 to find how much money he saves28.99 · 0.30 = 8.697. This rounds up to $9.
Therefore, The answer is C: $9.
For the second one, first divide 92 by 10 to find out how much one fence post costs. One fence post costs $9.2. Now, divide 276 by 9.2 to find how many fence posts he bought.
276 ÷ 9.2 = 30.
Mr. Bell bought 30 fence posts.
Hope this helped!
