Question

abdul purchases two pairs of goggles priced the same, as well as a bottle of sun screen. The sunscreen was $12 and represents 30% of the total. How much is the purchase total?

Answer 1

$40

Explanation:

We can call the total x.

30% = 3/10, so $12 = 3/10 of the total.

This means that 12 = 3/10 of x, or 12 = 3/10 * x.

Solving,

12 = 3/10 * x

multiply both sides by 10 to get rid of the fraction

120 = 3 * x

divide both sides by 3 to get x, the total, by itself

40 = x

This means that the total is $40.

Answer 2

• $40

Explanation:

Let the total be x

• 30% of total is $12
• 0.3x = 12
• x = 12/0.3
• x = 40

Total is $40
