Emily is 46 years old. Colin is 11 years older than Emily. Dan is 5 years younger than Emily. What is the total of their combine
Nonamiya [84]

Answer:

144

Step-by-step explanation:

<u>Data:</u>

<em>Emily's age</em> : 46 years old

<u>Find Colin's age</u>

<em>Colin's age</em>: 11 years older than Emily

                    Emily's age + 11

                    46 + 11 = 57 years old

<u>Find Dan's age</u>

<em>Dan's age</em>: 5 years younger than Emily

                  Emily's age - 5

                  46 - 5 = 41 years old

<u>Find their combined ages</u>

<em>Combined ages</em>: Emily's age + Colin's age + Dan's age

<em>Combined ages </em>= 46 + 57 + 41

Total = 144

Therefore, the total of their combined ages is 144.
