Caleb purchases 5 beach towels for d dollars each. Each towel is charged an additional 6% sales tax.

Which expressions can Caleb use to find the total cost of all 5 towels?

Select each correct answer.

5.3d

5d + 0.3d

5 (d+0.06d)

5d + 0.06d

The correct expressions are:

5.3d

5d+0.3d

5 (d+0.06d)

Since he is purchasing 5 towels that have a cost of d dollars each, the cost of the towels is given by 5d.

However, to add 6% tax, we multiply this by 0.06 and add it to the price without tax:

5d+0.06 (5d)

Simplifying this, we have 5d+0.3d = 5.3d.

All of the correct answers simplify to this expression.
