1 yd = 3 ft

This means the unit cost per feet is $4.99/3.

Let 'x' represent the length of the material in feet that you can be with $30.

(4.99/3)*x <= 30

I'll be able to buy 18 feet of material

Let the total materials that can be bought be represented by x.

Note that 1 yard = 3 feet

Therefore $4.99 per yard means $4.99 for 3 yards.

Therefore, based on the information given, the equation will be:

4.99/30 = 3/x

Cross multiply

(4.99 × x) = (30 × 3)

4.99x = 90

x = 90/4.99

x = 18

Therefore, I'll be able to buy 18 feet of material
