1. Lucita works at a fitness center and earns $5.50. per hour. She worked 3 hours on Friday and x hours on Saturday. Write an expression to represent her total wages earned.
5.50(3)+5.50x
2. You and your friend spend a total of $15 on lunch. Your friend's lunch cost $3 more than yours did. How much did you spend for lunch?
$6
Right.
1. Yes, or 5.50(3 + x)
2. Correct.
Let S be what you spent.
Then S+3 is what the friend spent.
S + (S+3) = 15
2S + 3 = 15
2S = 12
S = 6
So yes 6 is correct. Good job.:)
Thank you all :)
Welcome.
To find out how much you spent for lunch, we can start by setting up an equation. Let's say you spent x dollars for lunch. According to the given information, your friend's lunch cost $3 more, which means they spent x + 3 dollars. The total cost of both lunches is $15.
So, we can write the equation as follows:
x + (x + 3) = 15
Combining like terms, we have:
2x + 3 = 15
Subtracting 3 from both sides:
2x = 12
Finally, dividing both sides by 2 gives us:
x = 6
Therefore, you spent $6 for lunch.
