Answer:
256, 1024, 4096.
Step-by-step explanation:
The rule is x*4.
--> 1*4 = 4.
--> 4*4 = 16.
--> 16*4 = 64.
--> 64*4 = 256.
--> 256*4 = 1024.
--> 1024*4 = 4096.
Okay, let's find out how much the tax was by finding out what 7% of $28 is, we do this by multiplying:

Convert 7% into a decimal, we do this by dividing it by 100 because percentages are parts of 100:

Multiply:

So this is the tax. Add it to the original price to get the total price:
0.4x + 3.9 = 5.78
1. Subtraction property of equality:
Subtract 3.9 from both sides of the equal sign:
0.4x = 1.88
2. division property of equality:
Divide both sides of the equal sign by 0.4:
X = 4.7
