Alannah is a student who is not old enough to work, but would like to make some money. She
Westkost [7]

Answer:

15 small bottles

30 large bottles

Step-by-step explanation:

Let the number of small bottle sold=s

Let the number of large bottle sold=l

She sold all 45 of the hand sanitizer bottles, therefore:

  • s+l=45

The small bottle sells for $5.00

The large sells for  $12.00

She collected a total of $435

  • 5s+12l=435

We solve the two equations simultaneously to obtain s and l.

From the first equation, s=45-l

Substitute s=45-l into 5s+12l=435

5(45-l)+12l=435

225-5l+12l=435

7l=435-225

7l=210

Divide both sides by 7

l=30

Recall: s=45-l

Therefore, s=45-30=15

<u>Allanah sold 15 small bottles and 30 large bottles of hand sanitizer.</u>

Find the difference and write it in simplest form 7 3/8 - 2 7/9
Papessa [141]
Well first you have to turn the mixed number into a improper fraction.
7 2/8=59 over 8
2 7/9=25 over 9
Then u would multiply the 59 by 9 and 8 by 9 and u should get 531 over 72 and for the second fraction u should multiply the 25 by 8 and the 9 by 8 and you should get 200 over 72 as a improper fraction.
Then you have to subtract 531 over 72 by 200 over 72 and u should get 231 over 72 which is 4 and 43 over 72 when simplified.
The answer: 4 43/72
Hope this helps!!!!

Arte-miy333 [17]

Answer:

mp=sp+25%ofsp=1.25sp

mp=1.25sp

sp=1/1.25×mp=0.8mp

cp=mp-30%ofmp=0.7mp

discount=mp-sp=mp-0.8mp=0.2mp

  1. discount %=discount/mp×100%=0.2mp/mp×100%=20%
  2. profit=sp-cp=0.8mp-0.7mp=0.1mp
  3. profit%=profit/cp×100%=0.1mp/0.7mp×100%=0.1×100/0.7%=10/0.7%=14.28%
