Answer:
22%
Step-by-step explanation:
1000-780=220
220/1000=0.22, or 22%


No, since 0 doesn't belong to the domain.
In this problem, we let x be the number of half gallons of milk the store bought, and x-12 be the remaining half gallonsWe use the equation profit = revenue-cost
88.08=4.02(x-12)-2.60x88.08=4.02x-48.24-2.6x1.42x=88.08+48.24=136.32x=136.32/1.42=96Hence, the number of half gallons of milk the store bought is 96
37.5 % of 800 is 300 because of division
