In general, a "C" grade tends to be equivalent to a percentage somewhere in the 70s. There is not one set standard, so it varies among schools. Each institution determines its own grading policies.
Know MoreFor example, at the University of Washington in Seattle, a "C" runs from 75 percent to 79 percent. An 80 is considered a "C" to "C+." At the other end of the scale, 73 or 74 percent is a "C-," while a 72 is a "C" to "D+." Other schools have slightly lower percentages for a "C." At the University of Northern Iowa in Cedar Falls, a "C" is 73 to 76 percent. A "C-" covers 70 to 72, while anything in the high 70s equals a "C+."

Full Answer >A $35 item that is marked 40 percent off has a final cost of $21. The markdown is calculated on its own before it is subtracted from the original price to determine the final total.
Full Answer >Twenty percent of 30 is 6. "Percent" means "per 100," or "divided by 100," so calculating 20 percent entails multiplying by 20 and dividing by 100, which is the same as multiplying by 0.20.
Full Answer >The product of 25 percent of 100 is 25. The best way to calculate percentages is to use what mathematicians call a proportion, which states that two ratios are equal to each other. All percentages can be converted into ratios using fractions in the following way: x % = x/100.
