your friend bought 3 bags of wild bird seed and an $18 bird feeder. each bag of birdseed costs the same amount. if your friend spent $45, find the cost of one bag of birdseed. a. 3 18x = 45; $2.33 c. 3 x 18 = 45; $24 b. 3x 18 = 45; $9 d. 3x - 18 = 45 ; $21
The total amount that your friend spent is the sum of the cost for 3 bags of wild bird seed and the bird feeder. By letting x be the cost of each bag of wild bird seed, the total cost for purchasing 3 bags of this is 3x. The equation that may be used to determine x is letter "B. 3x + 18 = 45". Each bag costs $9.
