Bob sold small and large beach umbrellas. small ones cost $10 each and large ones cost $25 each. one afternoon bob sold 10 umbrellas and made $190. how many of each size umbrella did he sell?

4 Small, 6 Large

Step-by-step explanation:

We can start by finding values that would help add our two prices together.

We know that each large umbrella is $25, so if we keep adding until we can add up the umbrellas to 10, then we'll get our answer.

1 Large: $25

2 Larges: $50

3 Larges: $75

4 Larges: $100

5 Larges: $125

6 Larges: $150

Now don't forget, we need 10 umbrellas in total, and we know that we need 4 more umbrellas to get to 10, and we need 40 more dollars to get to 190.

40/10 = 4

6 Larges, 1 Small = $160

6 Larges, 2 Small = $170

6 Larges, 3 Small = $180

6 Larges, 4 Small = $190
