If you're asking how many shirts he needs to sell in a month to start making a profit, the answer is:
t stands for amount of shirt
add how much he used for phone and print machine
35+25
$60+5.80t-10t=0
refine
60-4.2t=0
multiply both sides by 10
600-42t=0
600=42t
divide both sides by 42
t=100/7 which is approximately 14
Answer:
Step-by-step explanation:
Perimeter is twice the sum of the length and width
P=2(L+W), in this case
P=2(4x+6+3x+4)
P=2(7x+10)
P=14x+20

Answer:
s = -7.8
Step-by-step explanation:
from the question 12=10(s+4)+50
<u>first step</u>
open the bracket and evaluate for the value of s
12=10(s+4)+50
12 = 10s + 40 + 50
12 = 10s + 90
collect or combine the like terms
12-90 = 10s
-78 = 10s
divide both side by 10
-78/10 = 10s/10
-7.8 = s
therefor s = -7.8
