i have a word problem on systems of equations that i am completely lost on. my teacher says i have the right setup, i just need to eliminate a variable, which i know how to do, but im stuck on this question. HELP!!!!!!!!! Will MEDAL AND FAN
will post question once i have help
Molly's Custom Kitchen Supplies sells homemade forks and spoons. It costs the store $1.70 to buy the supplies to make a fork and $1.30 to buy the supplies to make a spoon. The store sells forks for $5.60 and spoons for 5.40. Last April Molly's Custom Kitchen Supplies spent $37.90 on materials for forks and spoons. They sold the finished products for a total of $147.20. How many forks and how many spoons did they make last April?

Best ResponseYou've already chosen the best response.0mmk. what i have so far is this: 1.70f + 1.30s = $37.90 5.60f + 5.40 = 147.20 my teacher says this is correct, i just need to evaluate now, and im stuck @imqwerty

Best ResponseYou've already chosen the best response.01.70f + 1.30s = $37.90 1.7f=37.91.3s f=(37.91.3s)/1.7 substitute this value of f in the second equation and u'll get the value of s then put the value of s in any of these equations to get the value of f

Best ResponseYou've already chosen the best response.01.70f + 1.30s = $37.90 multiply this equation by 5.6/1.7 u get (5.6/1.7)1.7f+(5.6/1.7)1.3s=(5.6/1.7)37.9 5.6f+(5.6/1.7)1.3s=(5.6/1.7)37.9 now subtract this equation from the second equation to eliminate 5.6f :) and then u'll be left with an equation with s.. can u solve it now?

Best ResponseYou've already chosen the best response.0so we have this 5.6f+(5.6/1.7)1.3s=(5.6/1.7)37.9 equation1 and we got another equation5.60f + 5.40s = 147.20 equation 2 subtracting equation 1 frm 2 u get 5.60f + 5.40s  [5.6f+(5.6/1.7)1.3s] =147.20 (5.6/1.7)37.9 5.60f + 5.40s  5.6f  (5.6/1.7)1.3s = 147.20 (5.6/1.7)37.9 5.4s(5.6/1.7)1.3s =147.2 (5.6/1.7)37.9 can u solve this equation to get s if ur stuck then don hesitate to ask :P :)

Best ResponseYou've already chosen the best response.0well we wanted to finish off the 5.6 f in the second equation by we had a 1.7f in the 1st equation so to make it 5.6f we multiplied the whole equation by 5.6/1.7 :)
