Final answer:
To find the sale price of the washing machine, calculate a discount of 1/3 off the regular price of $429, which is $143. Subtract this discount from the regular price to get the sale price, which is $286.
Step-by-step explanation:
The student has asked how to calculate the sale price of a washing machine after applying a 1/3 discount off its regular price of $429. To find the sale price, you need to calculate the amount of the discount and subtract it from the regular price. A 1/3 discount means you are saving the equivalent of one third of the original price.
First, calculate the discount amount: 1/3 of $429. You multiply 429 by 1/3 (which is the same as dividing by 3):
429 × 1/3 = $429 / 3 = $143.
Now, subtract the discount from the regular price:
$429 - $143 = $286.
The sale price of the washing machine is $286.
