Question

Cleo and her family fished for 3 days and caught 100 fish between them. They caught 12 fish on day 2 and 16 fish on day 3. How many fish did they catch on the first day.

Which equation is correct.
12x + 16 = 100
12x + 16 = 100

x + 12 + 16 = 100
x + 12 + 16 = 100

16x + 12 = 100

Answer 1

x + 12 + 16 = 100

72 fishes

Explanation:

Given parameters:

Number of days fished = 3days

Number of fishes caught = 100 fishes

Number of fish caught on day 2 = 12fishes

Number of fish caught on day 3 = 16fishes

Unknown:

Number of fish caught on the first day = ?

Solution:

Let the number of fishes caught on the first day = x;

Total number of fishes caught = No of fish on day 1 + No of fish on day 2 + number of fish on day 3

Insert the parameters and solve;

100 = x + 12 + 16

x = 100 - 28 = 72fishes
