An adult takes tablets containing 24 milligrams of zinc. if the amount is 160% of the recommended daily allowance, how many milligrams are recommended?

You would need to set of a ratio/proportion.

160/100 =24/x

you can reduce and make it to 8/5 = 24/x

the cross multiply 8x = 5(24)

so now it becomes 8x = 120

then we get the variable by itself by dividing by 8 on both sides, x = 120/8

so x=15, meaning 15 milligrams are recommended

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
