Answer 1

Hi Alina 

Go by the following steps

 

Let R = No. of roses sold

    T = No. of tulips sold

As given R =8+4T..... Eq 1

 

as price of each tulip is $2 and rose is $ 5

 

2T +5R = 414  .......... Eq 2

Now from these two equations we need to find T and S by substitution 

 

T= 17 and R = 76
