For a craft project, you select the four packages of modeling clay and the set of tools shown below. If there is a 6% sales tax, what is the total cost?

1.06 times the prices shown.

To calculate the total cost, we need to consider the cost of the modeling clay and the sales tax. Since we don't have the specific prices for the modeling clay packages and the tools set, let's use some random numbers for demonstration purposes.

Let's say the cost of each package of modeling clay is $5, and the cost of the tools set is $10.

First, let's calculate the cost of the modeling clay:
Cost of one package of modeling clay: $5
Number of packages: 4
Total cost of modeling clay: $5/package * 4 packages = $20

Next, let's calculate the sales tax:
Sales tax rate: 6%
Sales tax amount: 6% * Total cost of modeling clay = 6% * $20 = $1.2

Finally, let's calculate the total cost:
Total cost of modeling clay: $20
Sales tax amount: $1.2
Total cost: $20 + $1.2 = $21.2

Therefore, the total cost of the modeling clay and tools set, including sales tax, is $21.2.

To calculate the total cost, you first need to find the cost of the modeling clay and the cost of the tool set separately.

Let's assume the cost of each package of modeling clay is $x and the cost of the tool set is $y.

Since you have four packages of modeling clay, the total cost of modeling clay would be 4 times the cost of one package: 4x.

To find the total cost, you need to add the cost of modeling clay and the cost of the tool set, and then add the sales tax.

So the total cost would be: Total Cost = Cost of Modeling Clay + Cost of Tool Set + Sales Tax

The sales tax is calculated as a percentage of the total cost. In this case, the sales tax is 6%.

To calculate the sales tax, you can multiply the total cost by 6% (or 0.06).

So the total cost with sales tax would be: Total Cost with Sales Tax = Total Cost + (Total Cost * Sales Tax)

Now, you can substitute the values and calculate the total cost.
