The county superintendent of schools of each county with the approval of the county board of education, may make temporary transfers to a community college district which does not have sufficient money to its credit to meet current operating expenses from the county school service fund, in such amounts and at such times as he deems necessary. Such transfers shall not exceed 85 percent of the amount of money accruing to the district at the time of transfer. The amounts so transferred shall be repaid to the county school service fund prior to June 30 of the current year from any funds subsequently received by the district.
