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.
