7 * 0.04 = 7 * 4 *
7 times 0.04 equal 7 times 4 times ?

Solution

1 Cancel 77 on both sides

x\times 0.04=x\times 4xx×0.04=x×4x

2 Regroup terms

0.04x=x\times 4x0.04x=x×4x

3 Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}x

a

x

b

=x

a+b

0.04x={x}^{2}\times 40.04x=x

2

×4

4 Regroup terms

0.04x=4{x}^{2}0.04x=4x

2

5 Move all terms to one side

0.04x-4{x}^{2}=00.04x−4x

2

=0

6) Factor out the common term x

x(0.04-4x)=0

7 Solve for x

x=0,0.01

Done!

Step-by-step explanation:

$5.83 must receive in total to give a customer a ticket .

Step-by-step explanation:

As given

A seat to a musical costs $5.50.

To that amount must be added a 6% entertainment tax.

6% is written in the decimal form

= 0.06

Entertainment tax price = 0.06 × Musical seat cost

                                       = 0.06 × 5.50

                                       = $ 0.33

Thus

Total cost of the musical seat cost = Musical seat cost + Entertainment tax

Put all the values in the above

Total cost of the musical seat cost = $5.50 + $0.33

                                                         = $5.83

Therefore $5.83 must receive in total to give a customer a ticket .
