Answer:
Latisha worked 7 hours last week.
Step-by-step explanation:
First information: Last week, Eldon worked 4 hours more than Latisha.
E = Eldon's hours worked
L = Latisha's hours worked
E = L + 4
Second information: Together (Latisha and Eldon) earned $166. Then:
8L + 10E = 166
{E = L + 4
{8L + 10E = 166
8L + 10E = 166
8L + 10(L + 4) = 166
8L + 10L + 40 = 166
18L = 166 - 40
18L = 126
L = 7
