Answer:
its a
Step-by-step explanation:
Y = m x + b , where m is the slope. The slope is the rise over the run or the change in x ( rooms cleaned ) over the change in y ( cost ).
125 = m * 1 + b
175 = m * 2 + b
-----------------------
b = 125 - m
175 = 2 m + 125 - m
m = 175 - 125
m = 50 ( the rate of change ), b = 75
The formula is: y = 50 x + 75
It means that the starting cost will be $75 and that for every room cleaned, the cost will rise for $50.
The possible values (L,W): (1,7),(2,6),(3,5),(5,3),(6,2),(7,1)
Answer:
first prizes = $34
second prizes = $8
Step-by-step explanation:
8 × 3 = 24 100 - 24 = 76
76 ÷ 2 = 38
