Appliances at discount city are on sale for 70% of original price. eli has a coupon for an 18% discount on the sale price. if the original price of microwave oven is $500, how much will eli pay for the oven before tax?

70% plus 18% =88%
88% of $500 = $440
$500 minus $440 = $60
Eli will pay $60 for the oven before tax.

Hope this helped!

$500 x 0.3 = 150 - sale price
$150 x 0.18 = 27 - discount on sale price
150 - 27 = 123
$123

Hope this is correct!

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
