Mark went to a used CD store. He is buying a poster and several CDs. The poster costs $3 and CDs cost $10 each. He does not want to spend more than y dollars. Assuming there is no tax, which of the following inequalities represents this situation, where x is
the number of CDs purchased?
OA. $10 + $3x sy
OB. $3+$10x sy
OC. $10 + $3x2y
OD. $3+ $10x2y

a

step-by-step explanation:

the answer is a

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
