Ghella [55]

Answer: $69.75.


Step-by-step explanation:

Given: Cost of textbook before tax=$65.49

The tax on the textbook = 6.5%

∴ The tax amount = 6.5% of $65.49

=\frac{65}{1000}\times65.49=4.25685\approx4.26

⇒The tax amount = $4.26

The total cost of the textbook=Cost of textbook before tax+tax amount

=$65.49+$4.26

=$69.75

∴ The total cost of the textbook is $69.75.

How much coffee costing $4 a pound should be mixed with 3 pounds of coffee costing 4.50 a pound to obtain a mixture costing $4.3
AlekseyPX

Answer:

2 pounds of coffee costing $4 should be mixed with 3 pounds of coffee costing 4.50 a pound to obtain a mixture costing $4.30 a pound.

Step-by-step explanation:

Given that coffee costing $4 a pound mixed with 3 pounds of coffee costing $4.50 a pound . we have to find the number of pounds of coffee mixed with 3 pounds of coffee costing $4.50 a pound to obtain a mixture costing $4.30 a pound.

Let x be the pounds of coffee mixed.

Cost of coffee of 3 pounds costing $4.50 a pound is 3(4.50)=$13.5

Total weight of mixture=x+3

The cost per pound of the mixture will be the total value of the coffee in the mixture divided by the total weight of the mixture which is 4x+13.5 divided by total weight 3 + x.

∴ A/Q the equation becomes

\frac{4x+13.5}{3+x}=4.30

⇒ 4x+13.5=4.30(3)+4.3x

⇒ 0.6=0.3x

⇒ x=2

Hence, 2 pounds of coffee costing $4 should be mixed with 3 pounds of coffee costing 4.50 a pound to obtain a mixture costing $4.30 a pound.
