week at the grocery store?

$4.77

D. $6.93

Sorry, but there is no option of this answer but it is correct.  $64.80

Step-by-step explanation:

Step 1:  Make an equation

1.60 * (1 - 0.1) = n

1.60 * 0.9 = n

$1.44 per pound

Step 2:  Find the price

$1.44 * 45 pounds

$64.80

 Sorry, but there is no option of this answer but it is correct.  $64.80

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
