Laura ordered a set of blue and black pencils. she received 110 pencils, 20% of them were black. about how many blue pencils did she receive?

If 20% of the pencils were black, then 80 % percent of the pencils were blue.  (together they must equal 100)

110 *.80 = 88

88 pencils are blue

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
