Answer:

C. She did not follow order of operations.

Step-by-step explanation:

Order of operations says you always have to multiply before you add when solving an equation, unless there are parentheses. Meaning that she should have multiplied -9 and 2/5 first before adding -18, instead of adding -9 and -18 first.

NeX [460]

Answer: There were 212 robberies in 2012.

Step-by-step explanation:

Since we have given that

Number of robberies in Springfield in 2013 = 265

Rate of growth in 2013 = 25%

We need to find the number of robberies there were in 2012.

Let the number of robberies in 2012 be x

so, According to question,

$\frac{100+25}{100}\times x=265\\\\\frac{125}{100}\times x=265\\\\1.25\times x=265\\\\x=\frac{265}{1.25}\\\\x=212$

Hence, there were 212 robberies in 2012.
