Answer:
b. 11 apples; 1 orange
Step-by-step explanation:
We test each option, and see if the total is $3.50(what you spend). If the result is different, it is not a possible solution.
a. 1 apple; 11 oranges
1 apple for $0.20
11 oranges for $0.30 each
0.20 + 11*0.30 = $3.50
Possible solution
b. 11 apples; 1 orange
11 apples for $0.20 each
1 orange for $0.30
11*0.2 + 0.3 = 2.5
Not $3.5, so this is not a possible solution.
This is the answer
c. 7 apples; 7 oranges
7*0.2 + 7*0.3 = $3.5
Possible
d. 4 apples; 9 oranges
4*0.2 + 9*0.3 = $3.5
Possible
Answer:
10 easy levels and 10 difficult levels
Step-by-step explanation:
Given data
let the number of easy levels be x
and the number of difficult levels be y
so
x+y= 20----------1
and
3x+5y= 80------2
from 1
x=20-y
put this in 2
3(20-y)+5y= 80
60-3y+5y=80
2y=80-60
2y=20
y= 20/2
y= 10
put y= 10 in 1
x+10=20
x=20-10
x= 10
Hence Kiran played 10 easy levels and 10 difficult levels
