What is the equation?
In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
A tailor pays $10.25 per yard for wool and pays $5.75 per yard for cotton.
He bought 4.8 yards of cotton and spent a total of $85.00 on the two types of fabric.
Let x be the yards of wool did he buy.
The yards of wool did he buy is given by;
[tex]\rm 10.25x + 5.75 \times 4.8 = 85\\\\10.25 x=85-27.6\\\\10.25 x=57.4\\\\x=\dfrac{57.4}{10.25}\\\\x=5.6[/tex]
Hence, he buys 5.6 yards of wool, the correct option is B.
