A woman bought a bag of rice for 5700 and in 3 weeks later she could only buy ¾ of a bag for 5700, find the percentage increase.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

answer4 to the second power is 16

and 4 to the third power is 64,
