Answer:
Thy bought 150 Sweatshirts (x) and 250 tshirts (y)
Step-by-step explanation:
35x + 25y = 11500
x + y = 400
-25 (x + y = 400) Multiply by -25 to get the y's to disappear when you add the two equations together
-25x - 25y = 10000
<u> 35x + 25y = 11500 </u>
10x =1500
x = 150
Plug 150 in either equation for x to find y
150 + y = 400
y = 250
Answer:
Number of statues that can be painted are 17
Step-by-step explanation:
Initially Diana has
liters of paint remaining.
Every statue requires
liters of paint for painting.
We have to find how many statues we will be able to paint with this remaining paint.
To get the number of statues,
Number of statues = 
number of statues = 
=
= 17.5
Since the number of statues is not an integer the maximum number of statues that can be painted are 17.
