Answer:
$130.7086
Step-by-step explanation:
List price of phone answering system = $99.86
Handset cord = $8.95
Telephone wire = 45 cent/foot ; length = 50 feet
Rebate on phone system = $5
Store coupon =$1 of each accessory
Sales tax = 6% on final price
Price before coupon = (99.86 + 8.95 + (50*0.45)) =$131. 31
Number of accessories = 3
Total coupon = $5 + ($1 * 3) = $8
Price after coupon = final price : $131.31 - $8 = $123.31
Sales tax = 0.06 * $123.31 = $7.3986
Amount paid = $123.31 + $7.3986 = $130.7086
Answer:
y = 3x/2
Step-by-step explanation:
Let's solve for y first.
3y = -2x+6
y = -2x/3 + 2
We know that the slope is perpendicular to -2/3, meaning that we have to find the negative reciprocal of -2/3, which is 3/2.
y = 3x/2 + C.
We know the point (2, 3) and we plug that into our equation above.
3 = 3/2(2) + C.
3 = 3 + C
0 = C
C = 0.
We now plug in C for the equation, which gives us y = 3x/2.
