Given:
Cost of printing a catalog: flat rate of $52 and $0.20 per copy.
C = 52 + 0.20x
C is the total cost of printing x number of copies.
x = 500
C = 52 + 0.20(500) = 52 + 100 = 152
x = 1000
C = 52 + 0.20(1000) = 52 + 200 = 252
x = 1500
C = 52 + 0.20(1500) = 52 + 300 = 352
x = 2000
C = 52 + 0.20(2000) = 52 + 400 = 452
x = 2500
C = 52 + 0.20(2500) = 52 + 500 = 552
45/100
Simplify the fraction by diving by the largest possible factor
45 divided by 5 = 9
100 divided by 5 = 20
9/20
9/20 = 0.45
There are 27 boys on the playground.
Step-by-step explanation:
No. of Pre-K children = 34
No. of kindergarten children = 29
Total no of children = 29+34 = 63
Ratio of boys to girls = 3:4
Total ratio = 3+4 = 7
Therefore,
boys proportion = 
Total number of boys =
