Manufactured 50.88 pair. customer paid 90.10 and customer price included 6.25% sales taxes . what is the mark up?

The markup (in percentage) is 66.67%

The markup (in dollars) is $33.92

Step-by-step explanation:

First, we will find the sales price of the product (excluding sales tax).

Let sales price be "x", so we can say:

x increased by 6.25% is 90.10

Note:  6.25/100 = 0.0625

Thus, we can write an equation and solve for x now:

The markup is a percentage of the cost.

The markup is the difference in cost and sales price, divided by cost. Then we multiply by 100 to get percentage. So:

MarkUp =

The markup (in percentage) is 66.67%

In dollars, it will be $33.92

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
