Student purchased 7 binders for a total of $8.61. Write an equation that can be used to find the cost of each binder, n, in dollars. What is the cost, in dollars, Of each binder?

Answers:

The equation is 7n = 8.61

The cost of each binder is $1.23

Work Shown:

n = cost of one binder in dollars

7n = cost of 7 binders in dollars

7n = 8.61  is the equation

7n/7 = 8.61/7 ... divide both sides by 7

n = 1.23 is the cost of each binder

7n = 8.61

n = 1.23

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
