Answer:
(74/9,274/9)
Step-by-step explanation:
You have
x-5y=4 and
y=2x+14
so we subsitute y in the first equation
x-5(2x+14)=4
x-10x-70=4
-9x=74
x=74/9
so y=2(74/9)+14
y=148/9+14
y=274/9
so the oredered pair is
(74/9,274/9)
$210
because if it rose 30%, it's now 130% of what is used to be
or (what it used to be) ×1.3
so do the reverse and divide the new cost by 1.3
so 273÷1.3 which is 210
