Answer:
420
Step-by-step explanation:
Assuming this is the problem:
At a school, 147 students play at least one sport. This is 35% of the students at the school. How many students are at the school?
147/35 = x/100
35x=147*100
35x=14,700
x=420
Is it going to be $19.55?
144
20×12=240
add 4 to 20 and 12
makes a new rectangle 24×16
24×16=384
384-240=144
.50
the first is a linear
second is an exponential
third is quadratic
