Spencer paid for a sweatshirt with a fifty-dollar bill. The cashier gave him back 1 ten-dollar bill, 2 one-dollar bills, 1 quarter, and 2 nickels as change. How much did Spencer's new sweatshirt cost?

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
