An electronics store had a special sale on two different models of calculators. the more high-tech model sold for $33.02 and
the older model sold for $18.55. all together, 28 calculators were sold. total sales came out to $736.45. which system of
equations can be used to determine how many high-tech models were sold, x, and how many older models were sold, y?
a.
33.02x + 18.55y = 736.45
x-y=28
b.
33.02x + 18.55y = 28
x + y = 736.45
c.
33.02x + 18.55y = 736.45
x + y = 28
d.
18.55y = 33.02% + 28
x + y = 736.45

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
