Let I am interest, r rate, t time and p principle,
l= prt
l= 5500(.115)(5 )= $3162.5 is the total amount of interest to pay.
1/4a + 1/3a +8 =22
1st step add like terms:
1/4a +1/3a = 3/12a +4/12a = 7/12a
7/12a +8 =22
2nd step subtract 8 from each side:
7/12a = 14
3rd step divide both sides by 7/12 to get a:
a = 14 / 7/12
a = 24
