Answer:
Step-by-step explanation:
R means Rosa
given:
R+b+c=36
R R c-2=b, (R+2)+2=c
b-2=R, R+2=b
.
R+b+c=36 substitute for b and c
R+(R+2)+((R+2)+2)=36 add like terms
3R+6=36 subtract 6
3R=30 divide by 3
R=10
.
check
R=10
b=12
c=14
10+12+14=36
36=36
The final answer is 0.925, steps in the picture:

Answer:
The cost of both shirts and jeans after discount is $71
Step-by-step explanation:
Given as :
The number of shirts bought = 3
The number of pair of jeans bought = 2
The cost of each shirt before discount = $12
The cost of each pair of jeans before discount = $19
The discount on total cost = $3
Let The total cost paid = $A
<u>Now, According to question</u>
Total cost of items = number of shirts bought × cost of each shirt before discount + number of pair of jeans bought × cost of each pair of jeans before discount
Or, A = 3 × $12 + 2 × $19
Or, A = $36 + $38
Or, A = $74
<u>Again</u>
Discount of $3 is applied on total cost
So, The cost of items after discount = $74 - $3
Or, The cost of items after discount = $71
Hence, The cost of both shirts and jeans after discount is $71 Answer
