Question

Winston spent the day at the mall. First, he bought six bracelets for $40 each. Later, he returned two bracelets. After that, he bought four drones for $80 each. Write the total change to Winston's funds as an integer.

Answer 1

Total change in Winston's funds = $-480

Explanation:

• We know that the purchases and returns equals Winston's total change in funds.

Note that for every purchase, we make the dollar amount negative since he's losing money and for every return, we keep the money positive since he's gaining money back:

(number of bracelets purchased * -40) + (number of bracelets returned * 40) + (number of drones purchased * 80)

Since Winston bought six bracelets, returned two bracelets, and bought four drones, we can now determine the total change in his funds:

Total change = (6 * -40) + (2 * 40) + (4 * -80)

Total change = -240 + 80 - 320

Total change = -160 - 320

Total change = -480

Thus, the total change in Winston's funds is $-480.
