Question

Juanita is planting a flower garden. She wants to plant 24 tulips, and twice as many daffodils as tulips. A tulip plant costs $3 . A daffodil plant costs $2. What is the total cost of the tulip and daffodil plants?

Answer 1

The total cost is
`\$168`

Explanation:

Let

x-----> the number of tulips

y-----> the number of daffodils

C-----> the total cost

we know that

`x=24\ tulips`

`y=2x`

substitute the value of x

`y=2(24)=48\ daffodils`

Find the total cost

`C=3x+2y`

substitute

`C=3(24)+2(48)=\$168`
