The carpeting used in the living room cost Php13 per square yard on sale
and that used in the bedrooms cost Php 10 per square yard.
If the bedroom area used 20 yd² more than the living room,
let carpet used in living room be x sq. yards cost Php13 per square yard
the bedroom area used 20 yd² more
they used (x+20) sq. yards in bedroom. cost Php 10 per square yard.
Santos spent Php1468 on carpeting for their new home.
cost equation
13x +10(x+20) =1468
13x +10x +200=1468
23x = 1468-200
23x= 1268
x= 55.13 Living area sq. yards
55.13*13 = 716.69
Bedroom area = 55.13+20 = 75.13 sq. yards
75.13 *10= 751.30
So, the Santos spent approximately Php 716.69 on carpeting for the living room and approximately Php 751.30 on carpeting for the bedrooms.
check
10*75.13 +13*55.13 = 1467.99
