Question

The cost of a toy telephone is the same as the cost of 4 balls. Express the statement as a linear equation in two variables. Also, find the cost of getting 2 toy telephones packed, if cost of 1 ball is5and there is a fixed cost of 2 for packing a toy telephone

Answer 1

The cost of getting 2 toy telephones packed, if cost of 1 ball is 5 and there is a fixed cost of 2.for packing a toy telephone is Rs.44

Step-by-step explanation:

Let the cost of 1 ball be x

Cost of 4 balls = 4x

Let the cost of 1 toy telephone be y

We are given that The cost of a toy telephone is the same as cost of 4 balls.

So,y = 4xy=4x ---1

Now find the cost of getting 2 toy telephones packed, if cost of 1 ball is 5 and there is a fixed cost of 2.

Cost of 1 ball = 5

Cost of 4 balls = 4x = 4(5) = 20

So, By -- 1

Cost of 1 toy telephone = 20

there is a fixed cost of 2.for packing a toy telephone

So, Total cost of 1 toy telephone = 20+2=22

So,Total cost of 2 toy telephone = 22+22=44

Hence the cost of getting 2 toy telephones packed, if cost of 1 ball is 5 and there is a fixed cost of 2.for packing a toy telephone is Rs.44
