Margo makes jewelry with beads. Each necklace uses 48 beads. Each bracelet uses 22 beads. Margo wants to make 18 necklaces and 12 bracelets.
Which answer is the most reasonable estimate of the total number of beads she needs?
a. 1,000 because 40 * 20 + 20 * 10 = 1,000
b. 1,180 because 48 * 20 + 22 * 10 = 1,180
c. 1,400 because 40 * 30 + 10 * 20 = 1,400
d. 1,900 because 50 * 30 + 20 * 20 = 1,900
