Part A You will be given a scenario. Find the algebraic expression that could represent that scenario. Levi had a apples and then Lydia gave him 3 more. Lauren had 3 times the number of apples that Levi had. Levi had a apples and then he lost 3 of them on the way home. The product of a and 3.

Step-by-step explanation:

Part A

Here, the number of apples Levi initially had  = a

The number of apples given by Lydia  = 3

So, now the number of apples Levi has  = (a +3)

Now, the number of apple Lauren  has  = 3 x (number of apples Levi had)  

= 3 (a + 3)

Part B

Here, the number of apples Levi initially had  = a

The number of apples lost by Levi  = 3

So, now the number of apples Levi has  = (a - 3)

The product of a and 3 is 3 x a  = 3 a

78.59 is the mean
