Answer:
35 pounds of $8.00 tea and 15 pounds of $6.00 tea
Step-by-step explanation:
Let x represent the pounds of tea of the $8 kind. 8x would represent the total cost of that type of tea. We can also say 50 - x is the pounds of tea of the $6 kind, so 6(50 - x) is the total cost of that type of tea. 50 * 7.4 represents the total cost of all the tea, and the expression 8x + 6(50 -x) would also represent the same thing. We can write this as an equation,
8x + 6(50 -x) = 50 * 7.4
simplify,
8x + 300 - 6x = 370
2x + 300 = 370
and solve.
2x = 70
x = 35
This means there is 35 pounds of the $8 kind.
We can subtract that from 50 to find,
50 - 35 = 15,
15 pounds is the amount of the $6 kind.
If you have for example
19.90$ you round it as 20
if u have 19.05 you have it as 19 only because its not near to the next number to it
This problem can easily be completed if we go through it step by step.
1. Nick has a 15 minute ride home on the bus from school at 2:25 p.m.
2:25 p.m + 15 min = 2:40 p.m.
2. He goes on a 30 minute bike ride after arriving home at 2:40 p.m.
2:40 p.m + 30 min = 3:10 p.m.
3. He spends 55 minutes doing homework at 3:10 p.m.
3:10 p.m. + 55 min = 4:05 p.m.
Ergo, Nick finished his homework at 4:05 p.m.
Answer:
the cost of the three new CDs is $44.28
Step-by-step explanation:
Here in this question, we are interested in calculating the cost of 3 new CDs cost.
From the question, we already know the cost of one. The cost of three would be 3 multiplied by the cost of one.
The cost of the three excluding the sales tax = $13.79 * 3 = $41.37
The sales tax for the three pieces = 3 * $0.97 = $2.91
The cost of the three CDs including the sales tax = $41.37 + $2.91 = $44.28
