It is given that total profit is $
So,
..(i)
Given that the total number of prints is 
So,
..(ii)
using (i) and (ii),


Ok, so amy is 8 years older than twice alica's age
if amy=y and alica=x
y=8+2x
and sum is less than 32
y+x<32
we can subsitute 8+2x for y in other equation
8+2x+x<32
8+3x<32
minus 8 both sides
3x<24
divide both sides by 3
x<8
the inequality is x<8

Answer:
To find the scale factor, all you have to do is <em>divide a side value of one figure by its congruent side value on another figure. </em>
Step-by-step explanation:
To start:
- The values 15 and 10 are both for the same congreunt side --> EF and E'F'
- The values 4 and 6 are both for the same congreunt side --> DE and D'E'
- The values 4 and 6 are both for the same congreunt side --> DG and D'G'
- The values 8 and 12 are both for the same congreunt side --> FG and F'G'
So, to find the scale factor, all you have to do is divide the smaller congruent value from the larger congruent value.
Larger congruent value ÷ smaller congruent value = scale factor
15 ÷ 10 = scale factor
\____________________/
1.5
<h3>So, the scale factor is 1.5</h3>
To double check, we will use another congruent side to find the scale factor:
12 ÷ 8 = scale factor
1.5 = scale factor
<h3>So, the scale factor is most definitely 1.5</h3>
I hope this helps!
