Question

Mai, Scott, and Bob have a total of 98 in their wallets. Scott has 4 times what Bob has. Mai has 10 less than Bob. How much does each have?

Answer 1

Mai + Scott + Bob = 98

Let x equals the unknown.

Scott has 4 x Bob

Mai has Bob - 10

Let x = Bob and, replace the word Bob with the letter x.

Scott has 4x

Mai has x -10

Bob has x

Add what each person has and solve for x.

4x +(x - 10) + x = 98

4x + x - 10 + x = 98

6x - 10 = 98

6x -10 + 10 = 98 +10

6x = 108

6x/6 = 108/6

x = 18

Bob = $18

Scott has 4x. The means 4 times 18, and this is equals to $72

Scott = $72

Mai has x -10. This means 18 - 10 =$ 8

Mai = $8

18+72+8 = 98

Answer 2

B represents the amount that Bob has

4B represents the amount that Scott has

B - 10 represents the amount that Mai has

B + 4B + B - 10 = 98

Can you solve for B and answer?
