QuestionMr. Deluca has 30 students. He needs to buy packs of 10 string-cheese and 15 celery sticks. What's the minimum packs needed?

Studdy Solution

STEP 1

Assumptions1. String-cheese sticks are sold in packs of10. . Celery sticks are sold in packs of15.
3. Mr. Deluca wants to give each of30 students one string-cheese stick and one celery stick.
4. We need to find the least number of packs he should buy so there are none left over.

STEP 2

First, we need to find out how many packs of string-cheese sticks Mr. Deluca needs to buy. We can do this by dividing the number of students by the number of string-cheese sticks in a pack.
Number of string−cheese packs=Number of students/Number of string−cheese sticks in a packNumber\, of\, string-cheese\, packs = Number\, of\, students / Number\, of\, string-cheese\, sticks\, in\, a\, pack

STEP 3

Now, plug in the given values for the number of students and the number of string-cheese sticks in a pack to calculate the number of string-cheese packs.
Number of string−cheese packs=30/10Number\, of\, string-cheese\, packs =30 /10

STEP 4

Calculate the number of string-cheese packs.
Number of string−cheese packs=30/10=3Number\, of\, string-cheese\, packs =30 /10 =3

STEP 5

Next, we need to find out how many packs of celery sticks Mr. Deluca needs to buy. We can do this by dividing the number of students by the number of celery sticks in a pack.
Number of celery packs=Number of students/Number of celery sticks in a packNumber\, of\, celery\, packs = Number\, of\, students / Number\, of\, celery\, sticks\, in\, a\, pack

STEP 6

Now, plug in the given values for the number of students and the number of celery sticks in a pack to calculate the number of celery packs.
Number of celery packs=30/15Number\, of\, celery\, packs =30 /15

STEP 7

Calculate the number of celery packs.
Number of celery packs=30/15=2Number\, of\, celery\, packs =30 /15 =2

STEP 8

Now that we have the number of string-cheese packs and celery packs, we can add them together to find the total number of packs Mr. Deluca needs to buy.
Total number of packs=Number of string−cheese packs+Number of celery packsTotal\, number\, of\, packs = Number\, of\, string-cheese\, packs + Number\, of\, celery\, packs

STEP 9

Plug in the values for the number of string-cheese packs and the number of celery packs to calculate the total number of packs.
Total number of packs=3+2Total\, number\, of\, packs =3 +2

STEP 10

Calculate the total number of packs.
Total number of packs=3+2=5Total\, number\, of\, packs =3 +2 =5Mr. Deluca needs to buy5 packs in total.
