Answer:
The cost of cellphone is Php7,000.
Step-by-step explanation:
Cost of cellphone: B (Base)
Amount saved: 350 (Percentage P, or part of the base)
Ratio of amount saved to the cost: 5% or .05 or 5/100 (R)
Equation:
Derive the equation for B, base or cost of cellphone:
B = P/R
B = 350/.05
B = 7,000
The cost of cellphone is Php7,000.
Alternative solution using division of fraction:
B = 350 ÷ (5/100)
B = 350 × 100/5 (multiply the dividend by the reciprocal of divisor 5/100)
B = 35,000/5
B = 7,000
