Question

chandler and his friend alec recently bought new cell phones. alecs phone was 20% more expensive than chandlers. chandler also spent $37 on an extended warranty and $55 on a new phone case. both friends ended up spending the same amount of money. which equation can you use to find p, the price of chandlers phone? 0.2p + 55 = p + 37 p + 0.2p = p + 37 + 55 what was the price of chandlers phone? $

Explanation:

Step1: Simplificar la ecuación dada

Dada la ecuación $0.2p + 55=p + 37$.

Step2: Mover términos con $p$ al mismo lado

Restar $0.2p$ de ambos lados: $55=p + 37-0.2p$.

Step3: Combinar términos semejantes

$55 = 0.8p+37$.

Step4: Isolar el término con $p$

Restar 37 de ambos lados: $55 - 37=0.8p$, es decir $18 = 0.8p$.

Step5: Resolver para $p$

Dividir ambos lados por 0.8: $p=\frac{18}{0.8}=\frac{180}{8}=22.5$.

Answer:

$22.5$
