Question
Instructions: A) Identify the rate and the constant and construct an equation. B) Define what the variable is in each equation.
1. Karla builds 8 chairs a day.
2. Chang buys 2.5 acres of land every year. He owns 1.8 so far.
3. Kimmy works 2 hours of overtime a week. He so far has 6 hours logged in this month.
4. Marquise is trying to lose weight. He is 340 pounds right now. He loses about 7.5 pounds a month.
5. James has 14 homework assignments due. He completes 1 a day.
6. Hamza drinks 4 cups of coffee a day.
7. Lawrence eats 2 packs of Top Ramen a day. He has already eaten 5 packs.
Explanation / Answer
1. K = 8x
where x = no. of days and rate here is 8x
2. C = 2.5x+1.8
where x = no. of years, rate here is 2.5x and constant is 1.8
3. K = 2x+6
where x = no. of weeks, rate = 2x constant = 6
4. M = 340 - 7.5x
where x= no. of months, rate =-7.5x constant = 340
5. J = 14-x
where x= no. of days rate = x and constant = 14
6. H = 4x
where x=no. of days rate = 4x and constant = 0
7. L = 2x+5
where x=no. of days and rate=2x and constant =5
