Last Saturday Michaela rented 4 movies from the video store. This Saturday she rented 2 movies. Let x represent the cost of renting each movie. Write and simplify an expression for how much more Michaela spent last week renting movies.
Please help me work this out thanks
4x - 2x = 2x
To find out how much more Michaela spent last week renting movies, we need to calculate the difference between the cost of renting movies last week and the cost of renting movies this week.
Last week, Michaela rented 4 movies, and the cost of renting each movie is represented by x. Therefore, the cost of renting movies last week is 4x.
This week, Michaela rented 2 movies, and the cost of renting each movie is still represented by x. Thus, the cost of renting movies this week is 2x.
To find the difference, we subtract the cost of renting movies this week from the cost of renting movies last week:
Difference = Cost of renting movies last week - Cost of renting movies this week
= 4x - 2x
= 2x
Therefore, Michaela spent 2x more last week renting movies.
To find out how much more Michaela spent last week renting movies, we need to calculate the difference in the total cost of renting movies between the two Saturdays.
Let's start by finding the cost of renting movies last week. Last Saturday, Michaela rented 4 movies, so the total cost would be the cost per movie (x) multiplied by the number of movies (4). This can be expressed as 4x.
Now, let's find the cost of renting movies this Saturday. Michaela rented 2 movies, so the total cost would be the cost per movie (x) multiplied by the number of movies (2). This can be expressed as 2x.
To find the difference in cost between the two Saturdays, we need to subtract the cost of renting movies this Saturday from the cost of renting movies last week:
Difference = Last week's cost - This week's cost
= 4x - 2x
Simplifying the expression, we have:
Difference = 4x - 2x
= 2x
So, Michaela spent 2x more last week renting movies compared to this week.
