Cassie’s broker charges her a commission of $4.25 for every ten shares of stock bought or sold. cassie buys 92 shares of hyren airlines, 130 of giaco household goods, and 126 of iwad records. hyren airlines costs $13.70 per share, giaco household goods costs $3.28 per share, and iwad records costs $8.06 per share. to the nearest dollar, how much money did cassie spend in total? a. $3,851 b. $2,850 c. $2,702 d. $2,551

The answer is Letter B - $2,850. 

Multiply the number of shares to their respective costs per share. Add the results. Get the total number of shares then divide it by 10 before multiplying the result to 4.25. Add the product to the previous total.

   Hyren Airlines: 92 shares x 13.70 = 1260.4
   Giaco Household Goods: 130 x 3.28 = 426.40
   Iwad Records: 126 x 8.06 = 1015.56
   Total: 2,702.36
   Commission: (92 + 130 + 126) 348 shares / 10 shares = 34.8 x 4.25 = 147.90
   Total: 2702.36 + 147.90 = 2,850.26 or 2,850

First subtract 10 from both side
