You by a t shirt at the fair that costs the owner $12,but your markup is 30%. Tax is 7%. How much money do you owe
Ulleksa [173]

Answer:

The final price of money of t shirt that I own = $ 16.69

Step-by-step explanation:

Given in question as ,

The t shirt cost to the owner = $12

The markup percentage = 30%

So, now the cost price of t shirt = 30% of 12 + 12

                                                    = 3.6 + 12 = $15.6

Tax which is added now            = 7%

So, new cost of t shirt = 7% of 15.6 + 15.6

                                     = 1.092 + 15.6  =$ 16.69

Hence , the final price of money of t shirt that I own = $ 16.69   Answer

Quadrilateral ABCD is similiar to quadrilateral EFGH. The lengths of the three longest sides in quadrilateral ABCD are 60 feet,
babunello [35]

Answer:

15 feet

Step-by-step explanation:

It is given that Quadrilateral ABCD is similar to Quadrilateral EFGH. This means that the corresponding sides of these two quadrilateral will be in the same proportion.

i.e.

Ratio of two corresponding sides would be the same. We are given longest three sides of ABCD and shortest two sides of EFGH. Let the 4th sides of ABCD i.e. the shortest side be x.

So, the ratio of the shortest sides of two quadrilaterals would be the same as the ratio of second shortest sides.

So,

x:6=30:12\\\\\frac{x}{6}=\frac{30}{12}\\\\ x=\frac{30}{12} \times 6\\\\ x = 15

So, the 4th side on quadrilateral ABCD would be 15 feet. None of the options match with the answer.
