A store buys a refrigerator for $869.45 and marks the price up by 20%. What is the new price?
The markup price would be 20% of $869.45, which is $173.89.
So, the new price would be $869.45 + $173.89 = $1,043.34.
Therefore, the new price after a 20% markup would be $1,043.34.
The sales tax rate is 7%. If Trisha buys a swing set priced at $187, what will be the total cost including tax?
The sales tax on a purchase is calculated by multiplying the purchase price by the sales tax rate.
Sales tax on the swing set = 7% of $187 = 0.07 x $187 = $13.09
Total cost including tax = Purchase price + Sales tax
Total cost = $187 + $13.09 = $200.09
Therefore, the total cost including tax for Trisha to buy the swing set priced at $187 would be $200.09.
