Question 905279
c for calories in one cup of sunflower seeds.
c-400 is calories in one cup of raisins.


Account for the calories in the mixture made:
{{{2*c+3(c-400)=2900}}}
Solve.
{{{2c+3c-1200=2900}}}
-fixing
{{{5c=2900+1200}}}
{{{5c=(29+12)*100}}}
{{{5c=4100}}}
{{{highlight(c=820)}}}----calories in 1 cup SUNFLOWER SEEDS.
{{{highlight(c-400=420)}}}------calories in 1 cup RAISINS.
-
{{{cross(5c=(29-12)100)}}}----MISTAKE
{{{cross(5c=1700)}}}
{{{cross(highlight(c=340))}}}, <s>for the 1 cup of SUNFLOWER SEEDS.</s>





THIS ALREADY DONE:
I would guess that another tutor will catch the mistake, but so far, the description <s>seems wrong, because for the raisins, I would continue to find</s> {{{cross(c-400=340-400=highlight_green(-60))}}} calories.
