Question

HELPPP PLEASE!!Three friends went shopping. They each bought one pair of shoes that
cost $20 and 4 shirts that cost x dollars.
1. Write an expression that represents this situation.
2. Simplify the expression.

Answer 1

Answer:

1. $3 (20+4x)$

2. $60 + 12x$

Step-by-step explanation:

1. Let's just focus on one person at the moment. One of the friends bought a single shirt for $20, and 4 shirts that cost x dollars. Therefore, a single person's expense can be shown as:

$20 + 4x$

Where x is the number of shirts the person bought.

Each of the three friends had the exact same expenses too, so we multiply this by three:

$3 (20+4x)$

2. Simplifying the above equation just means multiplying each term in the parentheses by the 3 outside it, so 3 times 20 is 60, and 4x time 3 is 12x. Therefore, the simplified expression is:

$60 + 12x$

Hope this helps!
