Answer: $36 is discounted from the regular price
Step-by-step explanation:
<em>First, we need to take our given numbers</em>
<em>Originally </em><u><em>$90</em></u><em> </em>
<em>On sale for </em><u><em>%40</em></u>
<em>Let's now use this equation</em>
<em>90(n)</em>
<em>n will equal 0.40 due to it being %40 off</em>
<em>90(0.40)</em>
<em>$36</em>
Answer:
Step-by-step explanation:
Plugin x = 0 & y = -2 in the LHS of the equation. After substituting, if you get the RHS, then this point is the solution of the equation.
x - 2y = 0 - 2*(-2)
= 0 + 4
= 4 = RHS.
(0,-2) is solution of the equation.
Lets divide the problem in parts, first for sandwiches she used 3/4 out of 20 ounces of ham:
(3/4)(20) = 60/4 = 15
so for sandwiches Lauren used 15 ounces
Then for omelete she used 1/5, that is:
(1/5)(20) = 20/5 = 4
then Lauren used 4 ounces for omelete
So Lauren used 15 ounces for sandwiches and 4 ounces for omelete, that is 19 ounces in total, so there are left from the 20 original ounces:
20 - 19 = 1
there is 1 ounce of ham left
