Laura established a new flower garden, planting 4 tulip plants for every 1 rose plant, and no other plants. If she planted a total of 50 plants in the garden, how many of those plants were tulips?

Let T = number of tulips planted

Let R = number of roses planted

Laura planted 4 tulips for every 1 roseIn other words, the ratio of tulips to roses = 4 to 1

Or we can write: T/R = 4/1

Cross multiply to get:

T = 4RLaura planted a total of 50 plants in the gardenIn other words,

T + R = 50We now have 2 equations and 2 variables:

T = 4RT + R = 50When we solve the system (which I'll leave for you to do), we get: R = 10 and T = 40

Answer: 40

Cheers,

Brent
