Will bought 8 bagels and 5 muffins that cost him $28.85.gale went to the same store and bought 6 bagels and 7 muffins costing $26.09. abby went to the same store and bought 2 bagels and some muffins and spent $9.61. how many muffins did she buy?

Step-by-step explanation:

1. Set up the equations

 Let b = the cost of a bagel

and m = the cost of a muffin

You have a system of two equations:

2. Solve the equations

3. Calculate the number of muffins Abby bought

Let x = the number of muffins. Then

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
