kotykmax [81]

Answer:

16.5 hours

Step-by-step explanation:

The bicycle costs $240.  Eva already has $42.  She is making $12 per hour.

240 = 12x + 42

Solve for x to find out how many hours Eva needs to work to buy the bicycle.

240 = 12x + 42

240 - 42 = (12x + 42) - 42

198 = 12x

198/12 = (12x)/12

16.5 = x

Eva needs to work 16.5 hours to be able to buy the bikw.

A shop keeper has 8 gallons, 3 quarts,
ioda

Answer:

I believe it would be 86 cups left of milk.

Step-by-step explanation:

8 gallons= 128 cups of milk

3 quarts= 12 cups

Plus the 1 cup of milk he had equals 141 of milk in total

Now the customer wants 2 gallons (32 cups of milk), 5 quarts ( 20 cups), and 3 cups which is 55 cups of milk.

Now we minus what the customer bought from what the shop keeper had so:

55-141=86
