a $60
b $170
c $180
d $240
explain how you got your answer.

Explanation:

Step1: Find 50% of $120$

To find 50% of a number, we convert the percentage to a decimal (50% = 0.5) and then multiply it by the number. So, we calculate $0.5\times120$.
$0.5\times120 = 60$

Step2: Find the total money raised

We know Mrs. Kennedy's class raised $120$, and we just found that Mrs. Littelbrger's class raised $60$ (50% of $120$). To find the total, we add these two amounts together: $120 + 60$.
$120 + 60 = 180$

Answer:

The total money the two classes raised is $\$180$, which corresponds to option C (assuming option C is $\$180$ as per the calculation). The steps are: first, calculate 50% of $\$120$ (which is $\$60$) and then add it to $\$120$ to get the total of $\$180$.
