The minimum daily values (MDVs) for certain foods are given. They are based on
a 2,000 calorie per day diet. Find decimal and fractional notation for the percent
notation in each sentence.1 ounce of Tostitos provides9% of the MDV of fat.=9/100 .09
1/2 cupof Campbells’ New (d) 2 ounces of Star Kist tuna provide
England clam chowder provides 6% of the MDV of iron.=6/100 .06
2.Ms. Jordan has been given a loan of $2,500 for 1 year. If
the interest charged is $275, what is the interest rate on the loan=11%
3.A school had 900 students at the start of a school year. If there is
an enrollment increase of 7% by the beginning of the next year, what is the new enrollment?=963
To find the decimal and fractional notation for percent notation, you can divide the number by 100.
1. For 9% of the MDV of fat in 1 ounce of Tostitos:
- Decimal notation: Divide 9 by 100: 9/100 = 0.09
- Fractional notation: The decimal notation is already in fractional form as 9/100.
2. For 6% of the MDV of iron in 1/2 cup of Campbell's New England clam chowder:
- Decimal notation: Divide 6 by 100: 6/100 = 0.06
- Fractional notation: The decimal notation is already in fractional form as 6/100.
3. To calculate the interest rate on a loan:
- Divide the interest charged by the loan amount and multiply by 100.
- For Ms. Jordan's loan with $2,500 borrowed and $275 interest charged: (275 / 2500) * 100 = 11%
So, the interest rate on the loan is 11%.
4. To find the new enrollment after a 7% increase:
- Multiply the current enrollment by 1 plus the percentage increase.
- For a school with 900 students initially: 900 * (1 + 7/100) = 963
So, the new enrollment is 963 students.
