The sign at the right shows the costs for a deep-sea fishing trip. How much will the total cost be for 1 adult, 2 children, and 1 senior citizen to go on a fishing trip? Use mental math.
To calculate the total cost for 1 adult, 2 children, and 1 senior citizen, we add the costs for each category: 1 adult ($25) + 2 children ($18 x 2) + 1 senior citizen ($20) = $25 + $36 + $20 = $<<25+36+20=81>>81.
Therefore, the total cost for this group to go on a fishing trip would be $81.
To find the total cost for 1 adult, 2 children, and 1 senior citizen to go on a fishing trip, we need to add up the individual costs for each category.
From the sign, we can see that the cost for 1 adult is $50, the cost for 1 child is $25, and the cost for 1 senior citizen is $40.
So, the total cost will be:
1 adult: $50
2 children: 2 x $25 = $50
1 senior citizen: $40
Adding these amounts together, we get:
$50 + $50 + $40 = $140
Therefore, the total cost for 1 adult, 2 children, and 1 senior citizen to go on a fishing trip will be $140.
