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

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
