Answer 1

The account  A has amount $600 and B has $1600.

Step-by-step explanation:

The given equations are:

a+b=2200 ⇒1

0.03a+0.05b=98  or  $\frac{3}{100}a$+$\frac{5}{100}b$⇒2

Change the first equation by isolating a,

a = 2200-b. ⇒3

Apply equation 3 in 2,

$\frac{3}{100}(2200-b)$+$\frac{5}{100}b$=98.

66- $\frac{3}{100} b$+$\frac{5}{100}b$=98.

66+ $\frac{2}{100} b$ = 98.

6600+2b=9800.

2b=9800-6600.

2b=3200.

b=1600.

Substitute b value in equation 3

a=2200-1600.

a=600.
