The price of a coat is reduced by 15% in a sale. The sale price of the coat is £136.
Work out the price of the coat before the sale.

Step-by-step explanation:

Find 100% of the price:

100 - 15 = 85% (Sale price)

85% = 136

1% = 136 divide 85 = 1.6

100% = 1.6 x 100 = 160

Ans: £160

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
