Answer:

9/4 = x

Step-by-step explanation:

Combine the similar terms together on each side

similar terms being the same variable or just lone numbers

So:

3x + 4 -2 x - x = 4x - 5

3x -2x -x +4 = 4x -5

0x +4 = 4x -5

4 = 4x - 5

Next, make the variable term by itself on one side

So

4 = 4x -5

9 = 4x

9/4 = x

Cost of boots: $99.99 Markup: 9% What is the new cost
mote1985 [20]

Answer:

The new cost is $108.98

Step-by-step explanation:

Mark up is the amount that is added to cost price of a product for profit.

Given

Cost price of boots = C = $99.99

Mark up = 9%

First of all we will calculate markup and then add it to the cost price of boots to find the new cost.

Mark\ up = M = 9\%\ of\ 99.99\\= 0.09*99.99\\=\$8.99

The new cost will be:

C_n = Cost\ price + mark\ up\\C_n = 99.99+8.99\\= 108.98

The new cost is $108.98
