If 3 pounds (lb) of apples cost 90¢, what will 10 lb cost?
90 / 3 = 30 cents per pound.
0.3 * 10 = ?
To determine the cost of 10 lb of apples, we need to use the given information and perform some calculations.
First, we need to find the cost per pound of apples. We know that 3 lb of apples cost 90¢. To find the cost per pound, we divide the total cost (90¢) by the total weight (3 lb):
Cost per pound = Total cost / Total weight
Cost per pound = 90¢ / 3 lb = 30¢/lb
Now that we know the cost per pound, we can find the cost of 10 lb of apples. We multiply the cost per pound (30¢) by the weight of apples (10 lb):
Cost of 10 lb = Cost per pound * Weight of apples
Cost of 10 lb = 30¢/lb * 10 lb = 300¢
To convert the cost from cents to dollars, we divide by 100:
Cost of 10 lb = 300¢ / 100 = $3
Therefore, 10 lb of apples will cost $3.
