Question

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. ​

Answer 1

Part A:

The number of apples Levi has = (a +3)

The number of apple Lauren has = 3 (a + 3)

Part B:

The number of apples Levi has = (a -3)

The product of a and 3 = 3 a

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
