Identify the percent, amount, and base in this problem. what is 90% of 70? a) percent= 90%, amount= 70, base= unknown b) percent = 70%, amount = unknown, base = 90 c) percent = unknown, amount = 90, base = 70 d) percent = 90%, amount = unknown, base = 70

The answer here is D, Percent = 90%, Amount = unknown, Base = 70

We can solve this by using what we know. The first step is to note that 90 is the percent (since it has the percent sign). In addition, we know that 70 is the base (since we're taking a percent of 70). That gives us our answer of  D, Percent = 90%, Amount = unknown, Base = 70.

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
