Math Problem Statement

Belle had some roses and carnations. The number of roses was , of the total number of roses and carnations. After 247 carnations were sold, the number of roses became 5 of the total number of roses and carnations. How many more carnations than roses did Belle have at first?

Solution

Let the total number of flowers Belle had at first (both roses and carnations) be denoted by TT, and let the number of roses be RR. We are given the following information:

  1. The number of roses RR was one-third of the total number of roses and carnations, so: R=13TR = \frac{1}{3} T

  2. After 247 carnations were sold, the number of roses became five-sixths of the total number of flowers. Let the new total number of flowers after the sale of 247 carnations be T247T - 247. At this point, the number of roses is still RR, and we are told that: R=56(T247)R = \frac{5}{6} (T - 247)

We now have two equations:

  1. R=13TR = \frac{1}{3} T
  2. R=56(T247)R = \frac{5}{6} (T - 247)

Step 1: Substitute R=13TR = \frac{1}{3} T into the second equation

Substituting R=13TR = \frac{1}{3} T into the second equation: 13T=56(T247)\frac{1}{3} T = \frac{5}{6} (T - 247)

Step 2: Solve for TT

To solve for TT, first eliminate the fractions by multiplying both sides by 6: 6×13T=6×56(T247)6 \times \frac{1}{3} T = 6 \times \frac{5}{6} (T - 247) 2T=5(T247)2T = 5(T - 247) Now, expand the right-hand side: 2T=5T12352T = 5T - 1235 Subtract 2T2T from both sides: 0=3T12350 = 3T - 1235 Add 1235 to both sides: 3T=12353T = 1235 Now, divide by 3: T=12353=411.67T = \frac{1235}{3} = 411.67

It seems that this is not an integer, which indicates that there might be an issue with interpreting the problem's information.
