Answer:
Let s be the number of shorts and t be the number of T-shirts. s shorts cost $12s and t T-shirts cost $5t, then you have to find min and max value for the function f(s,t)=12s+5t.
The shaded domain (see image) is defined from the system of unequalities. The green lines are the graphs of function f(x,y) and it intersects domain in first point (0,5) (the minimum point) and in last point (20,0) (the maximum point). So,
.
Step-by-step explanation:
Find the discount price and subtract from the total to find the sale price.
To find the discount price, multiply 90 b 40% (convert 40% into decimal)
90 x 0.4 = 36
Next, subtract the discount from the total to find the sale price.
90 - 36 = 54
So, the sale price is <u>$54</u>.
In order to be a function, every x-value must correspond to only one y-value.
Answer: D
Answer:
The number of people who visited museum on Saturday is 558.
Step-by-step explanation:
Number of people went to museum on Monday = 186
Also, the number of people triples on Saturday.

= 3 x 186 = 558
Hence, the number of people who visited on Saturday is 558.
