Answer:
a) $49.48
b) $220921.91
Step-by-step explanation:
(a) 4 yd @ $12.37 per yd = 4 x $12.37 = $49.48
(b) 271 yd @ 815.21 per yd = 271 x $815.21 = $220921.91
(c) 20% yd @ $4.95 per yd : Here the nunber of yards are missing. Hence could not be answer . However if number of yards is x . The answer would be
20% of 4.95x
(20%=0.20)
0.20 × 4.95x
Answer:
1.75
c
+
2.25
a
=
1083.00
now we still know, that
a
=
508
−
c
so we can substitute it into the second formula
1.75
c
+
2.25
(
508
−
c
)
=
1083
now its just simple algebra
1.75
c
+
1143
−
2.25
c
=
1083
60
=
0.5
c
so:
c
=
120

Answer:
8.92
Step-by-step explanation:
14.52 - 5.6 =
less than means subtract
Walk = x + 6
Bike = x
Driven = x
x + x + x + 6 = 24
combine like terms
3x + 6 = 24
subtract 6 from both sides
3x = 18
divide both sides by 3 to isolate x
x = 6
Walk = x + 6 = 6 + 6 = 12
