Answer:
Step-by-step explanation:
Company A : 13 + 30m.....where m = # of mattresses
company B : 15 + 28m.....where m = # of mattresses
==============
company A : cleaning 4 mattresses : 13 + 30(4) = 13 + 120 = 133
company B: cleaning 4 mattresses : 15 + 28(4) = 15 + 112 = 127
so company B would charge less
==============
company A : cleaning 7 mattresses : 13 + 30(7) = 223
company B: cleaning 7 mattresses: 15 + 28(7) = 211
so by using company B, u would save : 223 - 211 = $ 12
(1454.625 mles)/(4.5 tanks) = 323.25 miles/tank
He gets 323.25 miles on a single tank of gas.
Answer:
52 in.
Step-by-step explanation:
Let the width = x.
The length is x + 18.
perimeter = 2(L + W)
244 = 2(x + x + 18)
122 = 2x + 18
2x = 104
x = 52
The width is 52 in.
