Solution for last week’s Math Madness question from 2/25/19: D) 4(38) + 4(0.83)
The fact that the perfume is 45% off means nothing considering that you are told the sale price. So at this point, all you need to find out is what the total cost for 4 bottles of perfume is at $38.83 each. This can be expressed by 4(38.83). This, however, is not an option of the given choices. You could take the easy route and choose option E, None of the above, or you can look a little harder at the choices. Option D is essentially the same as 4(38.83), just broken down. If you separate the dollars and cents and multiply them both by 4 then add them back together, you still get the same answer. Be careful with tricky questions and always check your answers!
