Question

Nori placed an order for 10 chairs that cost d dollars each and 2 tables that cost D dollars each. Write an expression for the total cost of the chairs and tables. 20d 10d + 2D 200 10D + 2d

Answer 1

Answer: Second option is correct.

Explanation:

Since we have given that

Cost of each chair be d dollar

Cost of each table be D dollar

Number of chairs = 10

Number of tables = 2

cost of 10 chairs become
`10* d=10d`

cost of 2 tables become
`2* D=2D`

So, the total cost of chairs and tables would be

`10d+2D=Total\ cost`

Hence, Second option is correct.
