Answer:
x =
y =
Step-by-step explanation:
2x = 10y - 8
3x + 4y + 5 = 0
2x = 10y - 8
x = 5y - 4
3x + 4y + 5 = 0
3 ( 5y - 4 ) + 4y + 5 = 0
19y - 7 = 0
19y = 7
y =
x = 5y - 4
x = 5 ( ) - 4
x =

Answer: Original price = $43.10, Increase = $19.40, Final price = $62.50
<u>Step-by-step explanation:</u>
Let x represent the original price, then
8x(1.45) < $500
x < $43.10
Increase is 0.45x
0.45($43.10)
= $19.40
Final price is Original + Increase
$43.10 + $19.40
= $62.50
