Q. Scarlett went shopping for a new phone. Sales tax where she lives is 5.75%. What number should she multiply the price of the phone by to find the total plus tax in one step?Answer:
Multiply by Total Factor: To find the total cost including tax in one step, Scarlett needs to multiply the price of the phone by a factor that includes both the original price and the sales tax. The sales tax is 5.75%, which means that for every dollar, an additional $0.0575 is charged as tax.
Add Original Price: To include the original price of the phone, we start with the number 1 (which represents 100% of the original price). To this, we need to add the sales tax rate expressed as a decimal.
Convert Tax Rate: The sales tax rate is 5.75%, which as a decimal is 0.0575. We add this to 1 to get the total factor.Total factor = 1+0.0575
Calculate Total Factor: Performing the addition gives us:Total factor = 1+0.0575=1.0575This is the number Scarlett should multiply the price of the phone by to find the total cost including tax in one step.
