A time-and-material ticket shows 3 electricians worked 7.5 hours each at $86/hour. What labor billing amount is supported by that ticket?
Correct Answer
A) $1,935
Labor billing is 3 x 7.5 x $86 = $1,935. Other choices use one worker, two workers, or an incorrect hour total.
Why This Is the Correct Answer
Labor billing is 3 x 7.5 x $86 = $1,935. Other choices use one worker, two workers, or an incorrect hour total.
Why the Other Options Are Wrong
Option B: $645
t&m labor billing, choice a: 7.5 x $86 gives $645. That calculation follows multiplies those two listed numbers.
Option C: $1,290
t&m labor billing, choice b: $1,290 backs into 15 when divided by $86; the accepted setup gives 22.5 on that same base.
Option D: $1,720
t&m labor billing, choice c: $1,720 backs into 20 when divided by $86; the accepted setup gives 22.5 on that same base.
Memory Technique
Picture a panel space labeled T&M labor billing: finish every operation before accepting $1,935.
