Answer:
Tomas is incorrect.
Step-by-step explanation:
Example : If we divide a cake into 8 pieces and a similar cake is into 4 pieces, a piece of cake taken from 4 pieces will be bigger than a piece taken from 8 pieces.
Similarly, size of 3 pieces of cake taken from 4 pieces will be bigger than the 3 pieces taken from 8 pieces.
Therefore, 
will be greater than 
.
Tomas is incorrect.
Set up the equation by writing the number of students in the ratio as a fraction:
3/4= (245-x)/x Cross multiply:
3x= 4(245-x) Multiply on right:
3x= 980-4x Add 4x on both sides:
7x= 980 Divide both sides by 7:
x= 140 this is how many girls there are. And:
245-140= 105= boys
50+30y
It is 30y because there are 7 days in a week and each week you deposit $5 so 5*7 is 30.
