unit #1 - lesson #5 warmup problem: fiona had a $25 gift card to a bagel shop. after buying 6 bagels, $2.50 remains on the gift card. set up and solve an equation for b, the cost of one bagel.

Answer

Explanation:

Step1: Set up the equation

The initial amount on the gift - card ($25) minus the total cost of 6 bagels (6b) equals the remaining amount ($2.50). So the equation is $25−6b = 2.50$.

Step2: Isolate the term with the variable

Subtract 25 from both sides of the equation: $-6b=2.50 - 25$. Then $-6b=-22.5$.

Step3: Solve for b

Divide both sides of the equation by - 6: $b=\frac{-22.5}{-6}=3.75$.

Answer:

$3.75$
