$120 per each student x 495 students = $59,400
Hope this helps!
4 × y - y = 36
4y - y = 36
Combining 4y and -y to get 3y
3y = 36
Dividing both sides by 3
y = 36/3
y = 12.
You can solve by subtracting: 500-330
but I like to use mental math and think this way:
she has 330
70 more will give her 400
and 100 more will give her 500
100 + 70 is 170.
1) 8,309,127 < 8,409,127
2) 3,000,003 > 223,646
1400, as 1200 + 200 = 1,400 and 1600 - 200 = 1400.
