A student spends the same amount each week for bus fare. In 5 weeks, he spends $115. Which equation shows this relationship? Let x=number of weeks and y=amount he spends. Hint: Write your answer in y=kx form where k=y/x. *

y = 23x

Step-by-step explanation:

Given

x=number of weeks

y=amount he spends

If a student spends $115 in 5 weeks, then;

when x = 5, y = 115

Substitute into the expression y = kx and get k

y = kx

115 = 5k

k = 115/5

k = 23

Substitute k = 23 into the expression y = kx

y = kx

y = 23x

Hence the  equation that shows this relationship is y = 23x

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
