Review: Jen sells flowers. She charges $2 per flower plug a $3 flat delivery fee. How many flowers did she deliver if she made $21?

Answers

Answer:

she delivers 9 flower plugs.

Step-by-step explanation:

in a standard equation the equation would be 21 = 2x + 3 and if you isolate the x you would have to first subtract the 3 from both sides and that would leave you with 18 = 2x and then you have to divide both sides by 2 and get 9=x

Starlin's goal is to spend less than $415 on a trip. So far, he has spent $25 on gas for his car. He will spend $100 each day on other expenses.

Let d represent the number of days for Starlin's trip.

Starlin's trip must last fewer than __ days.

Answers

Answer

Less than or equal to 4 days.

Step-by-step explanation:

Let D represent the number of days for Starlin's trip.  We know that Starlin has spent $25 on gas and will spend $100 for each day. So use the equation d=25+100d < 415. (We also know that Starlin plans on spending less than $415 on the trip, so if anything is above $415, we know it is the wrong answer.) Subtract 25 on both sides and then divide by 100; the equation should go like this:

25 + 100d < 415

25 + 100d - 25 < 415 - 25

100d < 390

d < 3.9

It would be wise to round to 4 unless otherwise specified.

I NEED HELP ASAP Catherine finds that in a randomly selected sample of 500 families in her home town, 45% own at least one computer. Her research shows that there are a total of 35,000 families in her town.

Which statements are true?

Select each correct answer.


To estimate the percentage well, she would need to collect data for all 35,000 families.

Since her sample was randomly selected, she can reasonably infer that about 45% of the 35,000 families in her town own at least one computer.

If she collected data for a random sample of 1000 families in her home town, then that percentage would be a better estimate for the percentage of all 35,000 families that own a computer.

Since her sample was only 500 families, it is not possible that the percentage is a good estimate for the percentage of all 35,000 families that own a computer.

. sells t-shirts for $2 and shorts for $4 in April the total sales were 600.00 people bought four times as many t-shirts as shorts how many t-shirts and shorts did they sell?​

Answers

Answer:

200 t-shirts and 50 shorts

Step-by-step explanation:

t= t-shirts

s = shorts

600 = 2t + 4s

t = 4s

600 = 2(4s) + 4s

600 = 8s + 4s    ––––> 600 = 12s

s = 50

t = 4(50) –––––> t = 200

check:

600 = 2(200) + 4(50)

600 = 400 + 200

600 = 600
