Let’s break this down step-by-step:
Step 1: Identify the values from the first equation
π’π’ + π’π’ + π’π’ = 30
Each pair of boots = 10
So,
π’π’ = 10 β One boot (π’) = 5
Step 2: Use this in the second equation
π§πΌ + π§πΌ + π’π’ = 20
We already know π’π’ = 10
So:
π§πΌ + π§πΌ = 10 β 2 Γ π§πΌ = 10 β
π§πΌ = 5
Step 3: Use this in the third equation
π₯Ώπ₯Ώ + π₯Ώπ₯Ώ + π§πΌ = 17
π§πΌ = 5
π₯Ώπ₯Ώ + π₯Ώπ₯Ώ = 12 β 2 Γ π₯Ώπ₯Ώ = 12 β
π₯Ώπ₯Ώ = 6 β One shoe π₯Ώ = 3
Step 4: Final equation
π’ + π§πΌ + π§πΌ Γ π₯Ώ
Pay attention to order of operations (PEMDAS): multiplication before addition.
We already know:
-
π’ = 5
-
π§πΌ = 5
-
π₯Ώ = 3
So:
π’ + π§πΌ + (π§πΌ Γ π₯Ώ)
= 5 + 5 + (5 Γ 3)
= 5 + 5 + 15
= 25
