Apen costs $2.09. it costs $0.45less than a marker. ken paid for one pen and one maker with a five-dollar bill. use a tape diagram with calculation to determine him change.

The amount of money to be received by Ken is .

Further explanation:

In the question it is given that the cost of one pen is and the cost of a pen is less than the cost of one marker.

Ken paid with a five dollar bill.

The objective is to determine the amount of change to be received by Ken.

Consider the cost of one pen as and the cost of one marker as .

It is given that the cost of one pen is so, the value of is as follows:

The cost of a pen is less than the cost of one marker.

The expression which represent the cost of one marker is as follows:

To obtain the value of substitute in the above equation.

Therefore, the cost of one marker is .

It is given that Ken paid for one pen and one marker.

So, the total amount of money to be paid by Ken is calculated as follows:

Ken paid his bill by giving five dollar.

The amount of change to be received by Ken is calculated as follows:

From the above calculation it is concluded that the amount of money received by Ken is .

Figure 1 (attached in the end) represents a tape diagram in which section I represents the cost one pen, section II represents the cost of one marker and the section III represents the amount of change received by Ken.

Thus, the amount of money to be received by Ken is .

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
