Accepted Solution

A:

Same exact thing as last time Bright! Devin has to multiply 28.99 by 0.30 to find how much money he saves

28.99 · 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!
