Need a little help with solving for which statement is true

Question

George began making paper flowers for the tables at the school awards banquet. He can make 3 flowers per minute. Sue joined him 5 minutes after he started. She can make 4 flowers per minute. George continued to make 3 flowers per minute. Together, they made 190 flowers. Which statement about the number of flowers made is true?

 

A. Sue made 160 flowers. B. George made 30 flowers. C. Sue made 25 flowers. D. George made 90 flower

Answer 1

m = minutes

George makes 3m flowers

Sue makes 4m flowers

 

George starts out 15 flowers ahead (5 · 3)

 

15 + 3m + 4m = 190

15 + 7m =190

7m = 175

m = 25

 

Sue makes 100 (4 · 25) flowers.

George makes 15 + 75 (3 · 25) or 90 flowers

 

D.
