Kitchen goods are on sale for 30% off their regular price. In addition, all goods are subject to 6% tax and a $6 shipping charge. If c represents the original cost of a blender, it’s total cost can be found using the expression 1.06(0.7 c) + 6. Explain where the coefficient 0:7 comes from. Someone please help this is for homework .

Total cost of the product can be find using the total cost price of the product deducing the amount of OFF sale (if any) also adding the taxes value (if any) and any other charges like installation charges and shipping charges.

For example:

If a product has cost price $100 and we have tax of 10% on all product also there is shipping charge of $10. Find the total cost.

Here, total cost = $100 + $ 0.1x100 + &10

total cost = $120.

Here, we have given that:

There is a 30% off sale on Kitchen goods.

All goods are subject to tax of 6%.

There is shipping charges $6.

If C represent the original cost of blender.

We have given the equation for total cost:

Total cost = 1.06 (0.7 C) + 6

here, 0.6 comes from the tax which is of 6%.

the addition 6 is the shipping charges.

and the coefficient C is the remaining price of the blender as Kitchen goods are on applying the 30% off sale. which is 100 - 30 = 70/100 = 0.7

Hence,

The coefficient 0.7 comes from the remaining price of the blender as kitchen goods are on applying the 30% off sale.
