To solve this problem, we first have to find our unknowns. Our unknowns are the number of beads she will have by the end of the summer and the number of beads each of her friends will receive. We can set up equations for these unknowns by letting represent the beads that she has at the end of the summer and represent the number of beads each of her friends will receive.

because she gets more beads by the end of the summer.

because she is splitting up her total amount of beads between friends. When you split something up evenly you divide.

This is an addition problem because we want to know how many total pieces of chocolate Zack ate all together. We can add or

The only sequence from above that adds each time is

The correct answer is 841. We start in the ones column on the far right and add 6 and 5. This is 11 so we have to carry the tens digit (1) to the next column and being the ones digit (also a 1) down. Adding the tens column we get

so once again we carry the 1 and bring the 4 down. Next we add the hundreds column which

which we bring down. Thus the final answer is 841.

Since Meredith is spending money over time, we need to add all four values together to find out how much she spent in all!
