After 24 days.

The label on a 1 1/2pound bag of wildflowers seeds states that it will cover an area of 375 square feet. Based on this informati

BaLLatris [955]

Answer:

250 square feet

Step-by-step explanation:

This problem can be easily solved using ratios.

It says that $1\frac{1}{2}$ pound covers 375 sq. ft.

So, how much would 1 pound cover?

Let 1 pound cover "x" pounds. We can setup up two ratios and equate them. Then cross multiply and solve for x.

Note: Pounds on numerator and Square Feet on denominator

$\frac{1\frac{1}{2}}{375}=\frac{1}{x}\\1\frac{1}{2}*x=375*1\\1\frac{1}{2}x=375\\\frac{3}{2}x=375\\x=\frac{375}{\frac{3}{2}}\\x=375*\frac{2}{3}\\x=250$

Hence, 1 pound of wildflower seeds will cover an area of 250 square feet
