let no of optional feature cost $23.99 = x
and no of optional feature cost $120.84 =y
therefore according to question
x+y=12 ..........(1)
23.99x + 120.84y = 675.28 ..........(2)
now continue........
Hey Everyone,
I am unsure how to solve the following problem, could you please show me how it's done so that I can solve similar problems in the future?
Melissa bought a new car with 12 optional features to the car. Each optional feature costs either $23.99 or $120.84. If she paid $675.28 for all the optional features, how many of each type did she buy?
Thanks in advance!
for only one variable,
let no of optional feature cost $23.99 = x
therefore no of optional feature cost $120.84 =(12-x)
(because total no. of options are 12)
23.99x + 120.84(12-x) = 675.28 .................(1)
(Melissa paid = total for optional feature cost $23.99 +total for optional feature cost $120.84)
now solve for x
