Question

the price of a skateboard is $63. you have a coupon that lowers the price by 20%. what is the price of the skateboard after using the coupon? write a decimal equation to solve for 80% of 63. 80% of 63 =? \boxed{\quad\quad} \cdot \boxed{\quad} =?

Explanation:

Step1: Convert percentage to decimal

80% as a decimal is $0.8$ (since to convert a percentage to a decimal, we divide by 100, so $80\div100 = 0.8$).

Step2: Set up the multiplication

We need to find 80% of 63, so the equation is $0.8\times63 =?$.

Step3: Calculate the product

$0.8\times63 = 50.4$.

Answer:

The decimal equation is $0.8\cdot63 = 50.4$, and the price of the skateboard after using the coupon is $50.4$.
