Question

A daycare center in Stafford currently has 9 assistant caregivers and 2 senior caregivers. Since demand is high, the owner is going to be hiring 2 assistant caregivers per month and 3 senior caregivers per month. Her goal is to have a larger staff, including an equal number of assistant caregivers and senior caregivers. How long will that take? How many of each type will there be?

Answer 1

9+2M = 2+3M

M = 7 months when there will be an equal number of assistant and senior caregivers

= 23 each = 9+14 = 2+21
