The answer is B. Hope this helps!(:
Answer:
Step-by-step explanation:
Let x represent the amount of medical bills that Giselle has to pay.
Assume she has over $160 in bills,
it means that
x > 160
Under plan A, Giselle would have to pay the first $110 of her medical bills, plus 35% of the rest. Therefore, she will have to pay for
35/100 × (x - 110) = 0.35(x - 110)
Under plan B, Giselle would pay the first $160, but only 20% of the rest. Therefore, she will have to pay for
20/100 × (x - 160) = 0.2(x - 160)
Therefore, the amount of medical bills that plan B will save is
0.35(x - 110) - 0.2(x - 160) = 0.35x - 38.5 - 0.2x + 32
0.15x + 6.5
Substituting x = 160 into 0.15x + 6.5, it becomes
0.15 × 160 + 6.5 = $30.5
Total bills would be 160 + 30.5 = 190.5
Therefore, Giselle would save $30.5 with plan B if she had more than $190.5 in bills.
Answer:
Building depth = 168 ft
Step-by-step explanation:
we must find the relationship (scale) of the model with respect to the building
.
wide-m (model) = 3 in
deep-m(model) = 4 in
wide-b (building) = 126 feet
deep-b(building) = x
the measures must be standardized
let's convert feet to inches
12 in → 1 feet
3 in → ?, then
3 in → 0.25 feet and 4 in → 1/3 feet
now deep-m = x

The answer is .005 because five out of one thousand need to be replaced.
Answer:
x=51.50-8y eqn (i)

from eqn (i) and (ii)

206-32y=39.50-y
166.5=7y
y=23.78
now putting the value of y in eqn (ii) we get
x=3.93
