Answer:
Step-by-step explanation:
Cost of 4 oranges = $x
cost of 1 orange= x/4
Cost of 10 oranges = x/4*10 = $ 2.5x
Cost of a custard apple = $1.25
Cost of n custard apple = 1.25*n = 1.25n
Cost of 4 bananas = $3
Cost of a banana = 3/4 = $0.75
Cost of (3n +1) bananas = 0.75*(3n+1) = 0.75* 3n + 0.75*1 = 2.25n + 0.75
Cost of fruits = 2.5x + 1.25 n + 2.25n + 0.75
= 2.5x + 3.50n +0.75
Answer: 500
Step-by-step explanation:
let we suppose x people went to the fair on Sunday.
now number of people attend the fair on monday=x-15%of x.
x-15x/100=100x-15x/100
85x/100
A/q
85x/100=425
85x=42500
x=42500/85
500
so, 500 people. attended the fair on sunday
Answer:
The answer is 3-1/9 is the answer.
X=120+angle a. will be your answer.
To complete the 100% of (the job) washing, Roland needed 4 Hours & Sam, 3 hour,
Mind you 100% = 1
Find for each one the (job) achieved in 1 hour:
Roland achieved 1/4 & Sam 1/3 each one in 1 hour.
In one hours both will achieve 1/4+1/3 =7/12
So they will complete 7/12 (of the job) in 1 hour & for a time = t they will complete 100% (or 1) of the job, that is 1/t =7/12 & t=12/7 =1.71 hour
