Which table shows a proportional relationship between x and y?

Letter a shows a proportional relationship

$57.40

Step-by-step explanation:

There are two different ways to solve this, so I’ll explain both of them in case you need them in the future!

(1) Case 1:

Since 100% of $82.00 is $82.00, and we want to find the price when 30% is not included, there is 100%-30% = 70% of the initial cost in the final answer. We can multiply $82.00 by the decimal equivalent of 70/100 (0.7) to find that the discount makes the cost $57.40!

(2) Case 2:

To take a bit of a longer approach, you can calculate what 30% of the cost of $82.00 is by multiplying:

$82.00 x 30/100 = $24.60

Then, you would take that discount off of the initial cost:

$82.00 - $24.60 = $57.40
