Astudent spends the same amount each week for bus fare in 5 weeks he spends 115 which equation shows his relationship let's= number of weeks

Let c represent the cost of bus fare per week

                 5c = $115

                    c = $25

The student spends $25 per week for bus fare so the rate is $25

The equation to determine the total cost for "x" number of weeks is:

y = $25x

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
