Show all work to solve this problem. The budget for a new kitchen includes $3,000 for new kitchen equipment. The chef spent $90 of that money for new aprons. What percent of the money for new kitchen equipment was spent on aprons?
total budget = $3000
cost of apron = $90
so
peecentage of money spent on apron = ($90/$3000)*100%
= 3/100 * 100%
= 3%
so 3%of money was spent on apron

Answer:
Mr. Crosgrove tipped $3.84.
120 pens are not red pens.
She had to pay $270 in taxes.
Step-by-step explanation:
So, to find the percentage of something you convert the percentage to a decimal and then multiply.
For #1
He spent $48, and tipped 8%
to turn 8% into a decimal you bring in down two place values, so it is 0.08. You multiply 48 * 0.08 and you get 3.84.
Mr. Crosgrove tipped $3.84.
For #2
He has 150 flair pens and 20% are red. Multiply 150 by 0.2. You will get 30. Now we know that there is 30 red pens, but the problem is asking how much is not red pens. subtract 150-30 and you get 120, so that is the answer.
120 pens are not red pens.
For #3
She has $2,000 and had to pay 13.5% You have to turn 13.5% into decimal so bring place value down by two so it is now 0.135. Multiply 2,000*0.135 and you get 270.
She had to pay $270 in taxes.
Hope this helps!!
