Joe wanted to know more about how the cost of fertilizer for his lawn-care business was changing. The cost of a bag of fertilizer just increased from $8 to $15. What is the percentage increase of the price? Represent the change as a fraction, percent, and decimal.
price of a bag of fertilizer increased from $8 t0 $15 thus the price increase = $7 % increase = 7/8 * 100 = 87.5% in decimal = 0.875 divide by 100 in fraction = 875/1000
