Final answer:
To find the purchase total, divide the price of the sunscreen by 30% and then divide the result by 3 to find the price of one pair of goggles. The total purchase amount is $40.00.
Step-by-step explanation:
To find the purchase total, we need to calculate the price of the sunscreen using the given information. We know that the sunscreen was 30% of the total, and the price of the sunscreen was $12.00. So, we can set up the equation 30% of the total = $12.00. To find the total, we divide $12.00 by 30% (or 0.30), which gives us $40.00.
Since Abdul purchased two pairs of goggles priced the same, we can divide the total by 3 (including the sunscreen) to find the price of one pair of goggles. Dividing $40.00 by 3, we get $13.33. Therefore, the purchase total was $40.00.
