The expression shown is the cost a customer pays for an item, where c is the cost the store pays for the item and 0.85c is the 85% price increase the store adds to the item. Which expression is equivalent to c+0.85c

D. 1.85c

Step-by-step explanation:

The expression shown is the cost a custom pays for an item, where c is the cost the store which expression is equivalent c+0.85c?

A. 0.15c B. 0.85c C. 1.15c D. 1.85c

Given:

c + 0.85c

c standing alone has a coefficients of 1

The coefficients of 0.85c is 0.85

The two terms have the same variable c

Add both terms together

c + 0.85c

= 1.85c

Therefore,

c + 0.85c = 1.85c

D. 1.85c
