2.5x + 0.1x = 2.6x
2.6x - 0.01x = 2.59x
Here is your answer
Money saved on each successive day is-
$3, &5, $7....
Clearly it forms an AP,
where
a1= 3
common difference, d= 2
n=20
So,
using formula
Tn= a1+(n-1)d
T20= 3+(20-1)2
= 3+ 19×2
= 3+ 38
=41
So, money saved on August 20= $41
Sum of money saved upto August 20 =
n/2 (a1+T20)
= 20/2 (3+41)
= 10× 44
= $440

Answer:
19.2
Step-by-step explanation:
Let x be the missing number
2 1/2x =48
5/2x =48
x=48(2/5)
x=19.2
first is 86
we know because of the sum of the interior angles of a triangle being 180, and that 5 + 6 =180
