Question

the sales tax rate is 10%. if cody buys a trampoline priced at $53, what will be the total cost including tax? $

Explanation:

Step1: Calculate the sales tax amount

The sales tax rate is 10% or 0.10 in decimal. The price of the trampoline is $53. So the tax amount is $53 * 0.10.
$53\times0.10 = 5.3$

Step2: Calculate the total cost including tax

Add the tax amount to the original price. So total cost is $53 + 5.3$.
$53 + 5.3 = 58.3$

Answer:

$58.3$
