Question

Over the past eight months, Darlene has purchased $9,345.62 with her Friendly debit card. Which TWO items shown below can she buy using her cash back reward?

Answer 1

Darlene purchased $9,345.62 with her Friendly debit card, which gives her 1% cashback rewards.

Calculating the rewards, we have:

`1\cdot$($9,345.62$)/(100)=$93.4562`

She has $93.4562 available to purchase.

Now we have to look for TWO items that add up not more than $93.45

If we select jeans ($48.75), then she would have $93.45 - $48.75 = $44.70 remaining. Since no item costs less or equal to $44.70, she cannot purchase jeans.

Now let's try the necklace ($51.25). Since it costs more than the jeans, they cannot be purchased either.

Then she necessarily could buy the last to items, that is, the bathing suit and the video game. They add up to $46.30 + $45.99 = $92.29

She has $93.45, so she can purchase the bathing suit and the video game
