Jacob gives his son $30 for chocolate. His son spends $16 on dark chocolate and spends the rest on white chocolate. Each white chocolate costs $7. Write an inequality for the number of white chocolate he can purchase.
[(30 - 16) / 7] ≥ n
16 + 7n ≤ 30
To write an inequality for the number of white chocolates Jacob's son can purchase, let's assume he purchases x white chocolates.
Since each white chocolate costs $7, the total cost of the white chocolates can be calculated as 7x.
We know that Jacob's son spent $16 on dark chocolate, so the amount he spent on white chocolates is equal to the remaining money after purchasing the dark chocolate. The remaining money can be found by subtracting the amount spent on dark chocolate from the total amount Jacob gave him:
30 - 16 = 14.
Now we can set up the inequality:
7x ≤ 14.
This inequality states that the total cost (7x) of x white chocolates should be less than or equal to $14.
