Answer:

x = 10

Step-by-step explanation:

∆RSE ~ ∆FGE

SE/ GE = RE/ FE

45/ 12x-3 = 55/ 143

3/ 3(4x - 1) = 11/ 143

11(4x-1) = 429

44x-11 = 429

44x = 440

x =10

A man invests a total of $9,493in two savings accounts. One account yields 9% simple interest and the other 10% simple interest.

Agata [3.3K]

Answer:

$1850

Step-by-step explanation:

Given

The person invests a total of $9493
Amount invested in 9% Simple interest account =x
Amount invested in 10% Simple interest account= 9493-x
Earnings in Interest=$930.8

The simple interest formula

$S.I=\frac{P\times T\times R}{100}$

where

S.I is simple interest
P is principle invested
T is time period
R is rate of interest

There fore total interest

$=930.8= \frac{x\times 1\times 9}{100} +\frac{(9493-x)\times 1\times 10}{100}\\930.8=\frac{9x+94930-10x}{100}\\93080=94930-x\\x=94930-93080\\x=1850$

Therefore x=1850

⇒Amount invested in 9% account= $1850
