Answer:
2x+10
Step-by-step explanation:
Hi there!
To represent last weeks sale, you would have f=x
x= the number of hot dogs he sold last week
Now, to get the expression of this week, you know that he sold TWICE as many as last week, and we know that x represents last week's sale, so you would get 2x.
2 represents twice the sales of the last week, and x represents last week's sales.
But then you also know that he sold 10 more. So he sold twice as many as last week's hot dogs but he also sold 10 more. That's where you get 2x+10
Again, 2x represents twice as many sales this week and the 10 is the 10 more hot dogs he sold.
Really hope this helps!
