A bakery sells 5 bagels for 7.50.There is a proportion relationship between the cost and the number of bagels, Which equation represents the cost in dollars, c, for b bagels?

$1.5b

Step-by-step explanation:

If a bakery sells 5 bagels for $7.50, we are to find the equation that will represent the cost of b bagels. This can be gotten using the equality postulate as shown;

5 bagels = $7.50

b bagel = $c

Cross multiply

5*c = 7.50b

Divide both sides by 5

5c/5 = 7.50b/5

c = 1.5b

Hence  the cost of b bagel c is $1.5b
