We are given a model rocket which costs $24 and has a sales tax of $1.92 on it. We can find what percent of 24 is equal to 1.92 to find the percent of sales tax. 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 percent of 24 is equal to 1.92 by substituting a= 1.92 and w= 24 into the formula and solve for p% using the Properties of Equality.
Since 0.08 equals 8%, we can complete percent equation.
1.92= 8% * 24
We found that 1.92 is 8 % of 24. This means that the sales tax for this model rocket is 8%.
