Ivanhoe and Associates, a consulting service, recently received a bill for repairs on its computer system totaling $$2,468.$ Ivanhoe thinks

it may have been overcharged and is trying to recreate the components of the bill. She knows the hourly rate is $$88$ and $15$ hours of

labor was charged. She also knows $$756$ of parts were replaced.

Compute the material loading charge percentage the repair service used. $($Round answer to $0$ decimal places, e$.$g$.20\%.)$
