Mound Middle School wants to reward their students for exceptional attendance Students who have attended at least 90% of their virtual classes get to attend a virtual dance party during school. Ms. Mabel has 35 students in her class. The table below shows the attendance of five of those students.

x + y = 6000

0.03x + 0.05y = 220

Step-by-step explanation:

Given that :

Total principal amount = $6000

Account A:

Let principal = x

Rate = 3% = 0.03

Account B:

Let principal = y

Rate = 5% = 0.05

Interest earned at after one year = $220

Amount invested :

x + y = 6000

Simple interest = principal x rate x time

Interest earned

(x * 0.03 * 1 ) + (y * 0.05 * 1) = $220

0.03x + 0.05y = 220
