Answer:
Altogether, Greg spent $22.71.
Step-by-step explanation:
1) 5kg × $2.75 = $13.75
Purple beads: Spent $13.75
2) 1/2 kg = 1.5kg
1.5kg × $1.84 = $2.76
Orange beads: Spent $2.76
3) 2kg × $3.10 = $6.20
White beads: Spent $6.20
4) Add them all together.
$13.75 + $2.76 + $6.20 = $22.71
Hope this helps. :)
