Question

Vicki has 210 baseball cards and buys an additional 15 cards every week. Jeb has 275 baseball cards and buys an additional 10 cards every week. After how many weeks will Vicki and Jeb have the same number of baseball cards?

Answer 1

13 weeks

Explanation:

X = number of weeks

Vicki = 210 + 15(x)

Jet = 275 + 10(x)

210 + 15(x) = 275 + 10(x)

Find like terms

5x=65

Isolate the variable

5x = 65

5 5 65 divide by 5= 13

*If you need to check substitute 13 for x in the equation and see if it is correct*
