Answer:

one binder for $3.70

Step-by-step explanation:

The cost of 5 binders and 3 folders = $23.00

The cost of 5 binders and 1 folder = $20.00   [ 2 folders less ]

Cost of 2 folders = 23 - 20 = $3.00

Cost of 1 folder = \frac{3}{2} = $1.50

The cost of 5 binders = 20.00 - 1.50 = $18.50

The cost of 1 binder = \frac{18.50}{5}

                                = $3.70

The cost of one binder is $3.70

This is my question​
Talja [164]

Answer/Step-by-step explanation:

∆ABC is similar to ∆CDE. Therefore, the ratio of their corresponding sides are proportional.

This,

\frac{DE}{AB} = \frac{DC}{AC}

\frac{4}{3} = \frac{x + 3}{x + 1}

Solve for x

4(x + 1) = 3(x + 3)

4x + 4 = 3x + 9

4x + 4 - 4 = 3x + 9 - 4

4x = 3x + 5

4x - 3x = 3x + 5 - 3x

x = 5

Use the value of x to find AC and DC

AC = x + 1 = 5 + 1 = 6

DC = x + 3 = 5 + 3 = 8
