A combination of 3 erasers and 5 pencils cost $7.55. A combination of 6 erasers and 12 pencils cost $17.40. How much is each pencil?

9.85

Step-by-step explanation:

I subtract 17.40 and 7.55 to get 9.85 they just wanted to know how much the pencil cost not erasers.

C

Step-by-step explanation:

Assuming the triangles are similar then the ratios of corresponding sides are equal, that is

= ( cross- multiply )

2.4x = 13.44 ( divide both sides by 2.4 )

x = 5.6 → C
