If Josie buys 2.4 KG of beads for $3.25 per kilogram, how much will her beads cost?

  1. $7.80

  2. $8.40

  3. $780

  4. $10.00

The correct answer is: $10.00

To calculate the total cost of the beads that Josie buys, you need to multiply the price per kilogram by the total weight in kilograms. In this case, Josie is purchasing 2.4 kilograms of beads at a rate of $3.25 per kilogram. The calculation works as follows: Total cost = Cost per kilogram × Total kilograms Total cost = $3.25 × 2.4 When you carry out the multiplication, you multiply 3.25 by 2.4 to obtain the total cost. Doing the math gives you: 3.25 × 2.4 = $7.80 Since the question asks for the cost of the beads and $7.80 is the correct amount arrived at through this calculation, the indication that option D ($10.00) is the answer seems to stem from a misunderstanding of the arithmetic involved. The correct understanding shows that the cost of the beads is $7.80, not $10.00. Therefore, assessing the figures reveals a need for careful multiplication to arrive at the accurate total cost.
