Let's supposes the number of cups sold is <em>c</em>.

We can use an equation to solve this problem. Since both people are down some money, we will write the number they spent on supplies as negative, and use their rates as the unit rates for each side of the equation.

-35 + 1.50c = -20 + 1c
.05c = 15
c = 30

Thus, they will have to sell 30 cups.

Step-by-step explanation:

One way to solve this problem is to set up two expressions: one for your cost and one for your sales. You will break even when both expressions are equal. You can then solve by using inverse operations.

Three friends recorded, in different units, the lengths of the hopscotch paths they made.
ivann1987 [24]

From the options given, Dustin's hopscotch path was the longest in comparison to the other two friends.

<h3>How to find out who had the longest path?</h3>
  • Make sure all distances use the same units.
  • If necessary convert the distances.
  • Compare the distances.

Based on this, let's make sure all distances are in feet.

  • Cassey: 94 feet

  • Jasmin: 1100 in or 91.66 feet
  • Each inch is equivalent to 0.0833
  • 1100 x 0.0833 = 91.66

  • Dustin: 32 yards or 96 feet
  • 1 yard = 3 feet
  • 32 x 2 = 96 feet

Based on this, the person with the longest path is Dustin.
