Answer: 20 children

Step-by-step explanation:

<u>Given</u>

Year 4: 11 cannot swim

Year 5: 21 can swim

Year 6: 18 of 30 can swim

Total 96 children

Total 37 cannot swim

<u>First Step: find the number of people from year 5 who cannot swim</u>

  • There are 30-18=12 people who cannot swim in year 6
  • There are 11 who cannot swim in year 4
  • Thus, we use the total number [37]-[year 4+year 6]=37-23=14 people who cannot swim in the year 5

<u>Second Step: find the number of children in year 5</u>

  • There are 21 children who can swim
  • There are 14 children who cannot swim
  • 21+14=35 children

<u>Third Step: find the number of children in year 4 who can swim</u>

  • There are 30 children in year 6
  • There are 35 children in year 5
  • There are 11 children in year 4 who cannot swim
  • There are in total 96 children
  • 96-30-35-11=20 children in year 4 who can swim

Hope this helps!! :)

Answer:

1100

Step-by-step explanation:

price = 1500

discount= 15%

15% of 1500 = (15/100)*1500= 15*15= 225

so selling price = 1275

profit is selling price - cost price

1275 - CP = 175

CP = 1275-175= 1100

I didn't understand the calculator part of the question

Jackson runs a farm stand that sells bananas and grapes. Each pound of bananas sells for $1 and each pound of grapes sells for $
mars1129 [50]

Jackson sold 27 pounds of bananas and 12 pounds of grapes.

Given that Jackson runs a farm stand that sells bananas and grapes, and each pound of bananas sells for $ 1 and each pound of grapes sells for $ 2.25, and Jackson sold 15 more pounds of bananas than pounds of grapes and made $ 54 altogether, to determine the number of pounds of bananas sold and the number of pounds of grapes sold the following calculation must be performed:

  • 25 x 1 + 10 x 2.25 = 25 + 22.50 = 47.50
  • 26 x 1 + 11 x 2.25 = 26 + 24.75 = 50.75
  • 27 x 1 + 12 x 2.25 = 27 + 27 = 54

Therefore, Jackson sold 27 pounds of bananas and 12 pounds of grapes.
