Max and Sharifa are both saving to buy the same model of DVD player, which costs $99, including tax. Max already has $31.00 and decides to save $8.50 per week from now on. Sharifa already has $25.50 and decides to save $10.50 per week from now on. Who can pay for the DVD player first? Explain. (NEED TO SHOW WORK)

Sharifa can pay for the DVD player first.

Step-by-step explanation:

Max:

99 - 31 = $68 remaining

68 / 8.5 = 8 weeks

Sharifa:

99 - 25.5 = $73.50 remaining

73.5 / 10.5 = 7 weeks

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
