Solve this problem. A florist sells holiday bouquets that use roses and carnations in a ratio of 2 to 7. She receives a shipment of 343 carnations. How many roses will the florist need

Let roses be R and carnations be C

"in a ratio of 2 to 7" means that the ratio of R to C is 2 to 7, meaning you'll have to cross multiply to translate it algebraically

since C = 343 we plug 343 in :

ergo, she needs 98 roses

to make sure of the

"ratio of 2 to 7" is technically a fraction =>  

and since the ratio of the roses to the carnations is the same as we plug the values R = 98 and C=343:

check with calculator too, hope i helped <33
