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? Sue made 25 flowers. George made 30 flowers.

Answer 1

we get that after 5 minutes George has 15 flowers. So the equations that model the situation is

`\begin{gathered} 3t+4t+15=190 \\ 7t=190-15=175 \\ t=(175)/(7)=25 \end{gathered}`

as the time is 25 minutes we get that George made

`25\cdot3+15=75+15=90`

George made 90 flowers
