Answer:
1. 6.75x or (6.75, 1)
2. He buys 9 sandwiches.
Step-by-step explanation:
For the first one, we know that he pays $6.75 for each sandwich, so if x equals the number of sandwiches, when written out it would be 6.75x
For the second one, we have to divide it up and solve one step at a time, and when we start solving them, we will find the pieces to figure out the other problems. Let's start with how much he paid. We know that he paid $80, but we have to remember that he got change back. So to find out how much he truly paid, we subtract the 19.25 from the 80. When we do this, we get 60.75. Now, to find out how many sandwiches he got, we can use how much he paid for each one. We know that he paid $6.75 for each one, and in total he spent $60.75. So to find out, we can simply divide 6.75 into 60.75, and we get 9. So now we know that he bought 9 sandwiches.
I hope this helps :)
Answer: It costs $5.52 to Sam to buy 12 stamps.

73,815 - 48,968 = 24,847
24,847 more people live in Debra's town.
2x-24 = 68 2x = 92 so x = 46. Sarah is 22 and her mum is 46.
