Answer:
5 weeks
Step-by-step explanation:
Let x represent the number of weeks they have been saving
Create an equation that sets Cameron and Sams' savings equal to each other, then solve for x
4x + 20 = x + 35
3x + 20 = 35
3x = 15
x = 5
So, they will have saved the same amount of money after 5 weeks

Answer:
Therefore, Sara’s current age (5 years later) is 19 years old.
Step-by-step explanation:
Let xx be Sara’s age five years ago. Therefore, Sara’s aunt’s age 5 years ago is 4x4x.
The difference in their ages is a constant, no matter how many years have gone by. (Can you see why?)
4x−x=42
3x=42
x=42/3
x=14
14+5=19
Therefore, Sara’s current age (5 years later) is 19 years old.

Answer:
$1.50
Step-by-step explanation:
1. we know that its $240 per 160 hot dogs
2. make that a ratio - 240:160
3. simplify the ratio so that the amount of hot dogs is at one (so divide both sides by 160)
4. so 240/160 = 1.5 . 160/160 = 1
5. 1.5:1
6. so for every one hotdog, you pay $1.50
