y: original price (in dollars)
0.12y: amount of discount (in dollars)
sale price: y - 0.12y = 0.88y
sales tax on this sale price: (0.06)(0.88y)
final cost: 0.88y + (0.06)(0.88y) = 0.88y(1+0.06) = 0.9328y
You would do 150/15=10 since this is a percent change it to a decimal(.10) to check do 150x.10=15 and 15/.10=150
Answer:
2^7
Step-by-step explanation:
Dividing fractions with exponents means you subtract, so 2^6/2^4 = 2^6-4 =2^2
Multiplying numbers with exponents means adding the exponents, so 2^2+2^5 = 2^2+5 = 2^7
What do you mean?.. Do you mean: e.g. How many tens are in 12.476? So you basically have the 70 as ten right? Well you need to count from the first number (12). So the answer to that example would be 1247. Forget about the decimal point.
