OpenStudy (aripotta):

x + y = 15 2.26x + 1.96y = 32.7 x = 15 - y 2.26(15 - y) + 1.96y = 32.7 33.9 - 2.26y + 1.96y = 32.7 33.9 - 0.3y = 32.7 -0.3y = -1.2 y = 4 x + 4 = 15 x = 11

OpenStudy (phi):

why would you think you were wrong? First, you can check your solution... Second, you have laid it out nicely, and solved it using substitution. Looks good.

I would just post'em

OpenStudy (anonymous):

w+p = 15 (2.26w + 1.96p)/15 = 2.18 solve w+p=15 for either variable then substitute. w = 15-p (2.26(15-p) + 1.96p)/15 = 2.18 p = 4 Check: p = 4 w = 11 4+11 = 15 11*2.26 = 24.86 4*1.96=7.84 24.86+7.84 = 32.70/15 = 2.18 per lb
