Given
A tea that is 22% jasmine is blended with a tea that is 13% jasmine
Find out the how many pounds of the 22% jasmine tea are used to make 10lb of tea that is 19.3% jasmine.
To proof
Let us assume that the a tea that is 22% jasmine is blended = a
Let us assume that the a tea that is 13% jasmine is blended = b
Total amount of tea made = 10lb
the equation be
a + b = 10
as given
jasmine tea are used to make 10lb of tea that is 19.3% jasmine.
write 22% in the decimal form
= 0.22
write 13% in the decimal form
= 0.13
write 19.3% in the decimal form
= 0.193
than the equation be
0.22a + 0.13b = 0.193 × 10
on simplify
22a + 13b = 193
two equation becomes
22a + 13b = 193 and a + b = 10
multiply a + b = 10 by 13 and subtracted from the 22a + 13b = 193
we get
22a - 13a + 13b -13b = 193 - 130
9a = 63
a = 7lb
put this value in the a + b = 10
we get
7 + b = 10
b = 3lb
Therefore the 22% jasmine tea are used to make 10lb of tea that is 19.3% jasmine is 7 lb .
Hence proved
P is the principal amount, $5200.00.
r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
t is the time involved, 9....year(s) time periods.
So, t is 9....year time periods.
To find the simple interest, we multiply 5200 × 0.06 × 9 to get that:
The interest is: $2808.00
9(3x-9)-7-2x
27x-81-7-2x
25x-88
