Abel and Zöe’s grandparents opened a savings account for an equal amount upon the birth of each child. Now, the values of their
accounts could be found by the following expressions, where t represents the years since 2011. Abel: y = 1266. 77(1. 03)t Zöe: y = 1159. 27(1. 03)t Based upon this information, find the difference in the children’s ages. Abel is years older than Zöe. Suggestions: Find the ratio 1266. 77/1159. 26. What does that ratio represent in terms of powers of 1. 03? You also can graph both equations and figure out the shift.
