Answer:
10 weeks
Step-by-step explanation:
Given the following :
B-Innovative, Inc. :
one-time signing bonus = $4,100
Weekly pay = $1,095
Tech-O-Matic :
one-time signing bonus = $2,300
Weekly pay = $1,284
number of weeks (W) Evelyn must work so that the income earned at Tech-O-Matic is greater than or equal to the income earned at B-Innovative, Inc
Tech-O-Matic ≥ B-Innovative
Total earning :
Tech-O-Matic : 2300 + 1284w
B-Innovative : 4100 + 1095w
2300 + 1284w ≥ 4100 + 1095w
1284w - 1095w ≥ 4100 - 2300
189w ≥ 1800
w ≥ 1800/189
w ≥ 9.52
Evelyn must work for 10 weeks
