A baseball cost $7 and a baseball bat cost $27. With a 6.5% tax rate, what is the total cost of buying both items?
mestny [16]

Answer:

Total cost of buying both items is $36.21.

Step-by-step explanation:

We are given that a baseball cost $7 and a baseball bat cost $27.

Also, we are given a tax rate of 6.5%

Now, to find the total cost of both items we will find the individual costs of both items by applying tax rate on it.

<u><em>Cost of baseball after applying tax rate is given by;</em></u>

Since we know that by applying a tax on any item it's cost gets increased.

So, Cost of baseball after tax = Cost of baseball before tax + Amount of tax      

Amount of tax = Tax rate \times Cost of baseball

                        = 6.5% \times $7

                        = \frac{6.5}{100} \times 7 = $0.455

So, Cost of baseball after tax = $7 + $0.455 = $7.455

<u><em /></u>

<u><em>Cost of baseball bat after applying tax rate is given by;</em></u>

Cost of baseball bat after tax = Cost of baseball bat before tax + Amount of tax      

Amount of tax = Tax rate \times Cost of baseball bat

                        = 6.5% \times $27

                        = \frac{6.5}{100} \times 27 = $1.755

So, Cost of baseball bat after tax = $27 + $1.755 = $28.755

Now, <u>the total cost of buying both items</u> = Cost of baseball after tax + Cost of baseball bat after tax

                                = $7.455 + $28.755 = $36.21

Therefore, the total cost of buying both items is $36.21.

I have 47 nickels and dimes worth $4.20. How many of each type of coin do I have?
soldi70 [24.7K]

Answer:

37 dimes and 10 nickels

Step-by-step explanation:

let d = # dimes

let n = # nickels

we can set up a system of equations:

n + d = 47

.05n + .10d = 4.2

if we solve the first equation for 'n' we get:  

n = 47-d

now we can substitute this in for 'n' in the second equation:

.05(47-d) + .10d = 4.2

2.35 - .05d + .10d = 4.2

2.35 + .05d = 4.2

subtract 2.35 from each side to get:

.05d = 1.85

d = 1.85÷.05

d = 37

if d+n = 47 and d=37 then n = 10

Check:

.05(10) + .1(37) should equal 4.2

.50 + 3.7 = 4.2  [It Checks Out]

Rick buys a remote control cars to resell. He applies a markup of 10%.
cestrela7 [59]

Answer:

The selling price is $30.80

Step-by-step explanation:

Buying price = $28.00

Rick applies a mark up of 10%

The percentage of buying price is 100%

The percentage of selling price is 100% + 10% = 110%

So $28 = 100%

What about 110%?

Cross multiplying gives;

110/100 × $28 = $30.80

The selling price is $30.80
