Answer:

Total potassium intake required is 3400 milligrams

Explanation:

Let the total amount required be #t#

You have 15% already. This means that the amount yet to be taken is:

#(100-15)% = 85%#

so #" "85%t=2890#

write as:

#color(brown)(85/100 t=2890)#

Multiply both sides by #color(blue)(100/85)#

#color(brown)(color(blue)(100/85xx)85/100xxt=color(blue)(100/85xx)2890)#

#1xxt= 3400#
