Question 266546
Here is the original equation:
(i) {{{0.03y + 0.13(1000 - y) =0.40y}}}
step 1 - distribute the 0.13 to get
(ii) {{{0.03y + 130 - 0.13y = 0.40y}}}
step 2 - combine like terms on the left to get
(iii) {{{-0.10y + 130 = 0.40y}}}
step 3 - add 0.10y to get
(iv) {{{130 = .5y}}}
step 4 - divide to get
(v) {{{y = 260}}}
