Bayside ins. offers two health plans. Under A, Giselle would have to pay the first $190 of her medical bills, plus 35% o the rest. Under plan b, Giselle would pay their first $200, but only 25% of the rest. For what amount of medical bills will plan b save Giselle money? Assume she has over $200 in bills.
Giselle would save with plan b if she had more than $___ in bills
Round to the nearest whole number.

3x-8y=-71
what is the solution of the system?
(-5, 7)

The body mass index, I, can be used to determine an individual’s risk for heart disease. An index less than 25 indicates a low risk. The body mass index is given by the formula, or model, I=700w
H^2 where w=weight in pounds, and h=height, in inches. Jerome is 66 inches tall. What weights will keep his body mass index between 21 and 31?
Jerome’s body mass index will fall between 21 and 31 for the set of all weights such that ___ < W < ___
I’m assuming it says to round…
131 < w < 193
#10
Determine whether the ordered pair is a solution of the inequality.
(-4,9); 3x+y < -3
in this case, is the ordered pair a solution?
NO (check that it is < and not ≤, because that would change the answer)
#11
graph the inequality on a plane (table)
x+y<2

DASHED line
#15
41-(2x+4) < 2(x+1)+x
use set-builder notation to describe the complete solution.
{x x ______} round to the nearest tenth.
x > 7 (but you need to check that the original sign was < and not ≤)
#17
Soybean meal is 16% protein; cornmeal is 8% protein. How many pounds of each should be mixed together in order to get 320lb mixture that is 11% protein?
How many pounds of the corn meal should be in the mixture?200
How many pounds of the soybean meal should be in the mixture?120
#18
the perimeter of a rectangle is 62m. the length is 10m more than twice the width. Find the dimensions.
What is the length? 24 m (simply answer)
What is the width? 7 m
#20
solve
-6x -3.0
the solution is {x x __}
I think you have a typo here…
If it really is:
-6x ≥ -3.0
Then:
x ≤ 0.5
#22
solve by the substitution method
9m+n=32
m-8n+36
what is the solution of the system?
You have a typo here in the second equation…
I’ll assume it’s:
m-8n=36
The answer would be:
(4, -4)
#23

3 NO
-16 YES
-15 YES
-1 NO
