Question

victoria has 100 trading cards. every month she buys 10 more cards. will she have 160 cards in four months?

Answer 1

No, in 4 months she will have 140 cards.

Explanation:

If Victoria has 100 cards now, and adds 10 cards every month, she will have added 40 cards in 4 months.

10 x 4 = 40

40 + 100 = 140

Answer 2

No, she will have 140 cards in 4 months

Explanation:

the equations is:

f(x) = 100 + 10x

now x = 4

f(4) = 100 + 10(4)

f(4) = 100 + 40

f(4) = 140

140 does not = 60
