Answer:
Brushes= 8, Paint= 4
Step-by-step explanation:
Given: Total spending on paint and brush= $20
Cost of each paint= $4
Cost of each brush= $0.50.
Let´s assume the number of paint bought be "x"
∴ number of brushes bought is "2x".
Now, forming an equation to determine the number of paint and brushes bought.
⇒ [tex]\$4\times x+ \$0.50\times 2x= \$20[/tex]
⇒[tex]4x+x= 20[/tex]
⇒[tex]5x= 20[/tex]
Dividing both side by 5
⇒ [tex]x= \frac{20}{5}[/tex]
∴ [tex]x= 4\ unit[/tex]
Hence, number of paint bought is 4 units.
Next finding the number of brushes bought.
Number of brushes bought= [tex]2\times 4[/tex]
∴ Number of brushes bought= [tex]8\ units[/tex]
Hence, number of brushes bought is 8 units.
