hlo dear
the average temperature of sun,mon,tue,wed nd thrusday = 80 f
average temp = total temp / number of days
80= total tem / 5
80*5 = total temp
400f = total temp of sunday to thrusday
nd the average temp of monday,tuesday,wednesday,thrusday,friday nd saturday = 81 f
then
average = total temp / total days
81 = total temp / 6
total temp of monday to saturday = 81*6
= 486 f
here when we substract the total temp of sunday to thrusday from monday to saturday
then we find
the sum of the temp of sunday+friday+saturday = 486-400
= 86f
nd given
temp on sunday = 76 f
temp of saturday = 4 f more than friday
which means saturday = friday + 4
theb the equ is friday = x - 4 where let x = saturday's temp
then
76 + (x-4) + x = 86
2x = 86-72
x = 14/2
x = 7
then the tep of saturday = 7 f
