There are 80 pupils in Jaydon's year group. 30% walk to school. 15% cycle to school. The rest get a bus.
How many pupils walk to school?
go
Show me the answer
How many pupils get the bus?
go

walk is 24 people

bus is 44 people

Step-by-step explanation:

100% is 80

30% walk

15% bike

55% bus

work out 30%

so 50% is 40

25% is 20 (dived by 2)

5% is 4 (divide 50 by 10)

30% is 24

for bus do 50% is 40

5% is 4

55% is 44 (add)

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
