Question

Brinley has 128 inches of elastic. She needs a piece that is 16 inches longto make one headband. The equation 128=16h can be used to find h, thenumber of headbands Brinley can make. Use the equation to determine ifBrinley can make exactly 7, 8 or 9 headbands4

Answer 1

Given: The modelled equation of 128 inches of elastic and headband as below:

`\begin{gathered} 128=16h \\ \text{where h is the headbands} \end{gathered}`

To Determine: If Brinley can make exactly 7, 8, or 9 headbands

From the equation, we can determine the value of h as shown below:

`\begin{gathered} 128=16h \\ \text{divide both sides by 16} \\ (128)/(16)=(16h)/(16) \\ 8=h \end{gathered}`

Hence, Brinley can make exactly 8 headbands
