Question

1. a garden contains 135 flowers, each of which is either red or yellow. there are 3 beds of yellow flowers and 3 beds of red flowers. there are 30 yellow flowers in each yellow flower bed.

part a
if r represents the number of red flowers in each red flower bed, what equation could you use to represent the number of red and yellow flowers?
part b
write another real - world situation that your equation from part a could represent.

Explanation:

Step1: Calculate total yellow flowers

Total yellow flowers = $3 \times 30 = 90$

Step2: Define total red flowers

Total red flowers = $3r$

Step3: Set up total flower equation

Total flowers = red + yellow:
$$135 = 3r + 90$$

Create a scenario with 3 identical groups of an unknown item, a known total of a second item, and a combined total matching the equation structure.

Answer:

Part A:

$\boldsymbol{3r + 90 = 135}$ (or rearranged forms like $3r = 135 - 90$)

Part B:
