The total no of 7th-grade students who come to school by bike will be 49. Option B is correct.
Simplifying is making something easier to do or understand, as well as less difficult.
The table shows the following information;
There are 128 seventh-grade pupils in all.
The number of 7th grade pupils who take the bus is 79.
The overall number of 7th-grade pupils who commute to school by bus or bike is as follows:
Student via bus + Student by bicycle = Total number of seventh-graders
Let x be the number of seventh-grade students who ride their bikes to school, and the following equation is produced;
Students taking the bus + students riding their bikes = total number of seventh grade students
x+79=128
x=128-79
x= 49
There will be 49 7th grade pupils who ride their bikes to school
