There were 56 signers of the Declaration of Independence.
Practice makes perfect
We are told that the number of signers of the Declaration was n. We also know that n is 80% of y. In the previous exercise we found that y equals 70. Recall that the percent equation is an equation in which the part is equal to the product of the corresponding percent and the whole. We can represent a is p percent of wwith the following equation.
a= p% * wWe can find what 80% of 70 is by substituting p%= 80100 and w= 70 into the formula and solve for a using the Properties of Equality.
Knowing the value of a, let's look at the completed percent equation.
56= 80% * 70
We found that 56 is 80 % of 70. This means that there were 56 signers of the Declaration of Independence.
