Can anyone explain me the steps i have to do to get my answer ?

3.4% in decimal form is .034 = r
2014 - 2004 = 10 years = t

A = 45,000(1+.034)^10
A= 62,866

Multiply 45000 by 3.4% or 0.034 that equals 1530 * 10 = 15300 add it to 45000 =60300

A=45000(1+3.4%)

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
