Accepted Solution

A:

Answer:expression aStep-by-step explanation:The given expression is 15+0.25(d−1).let suppose,15 = a0.25(d−1) = bwe get a + bIt clearly indicates the given expression is sum of two entities, we can exclude option b and option d.Now we are left with option a and c, for that we have to evaluate the term bb = 0.25(d−1) that is the additional amount after d daysTherefore, expression a is correct.
