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
