Dan went to the bookstore .he has spent $17.00 of his $20.00 already .he needs to buy a few disk.how many can he buy with his remaining money if each disk cost 90 cents ?
3.00/0.9 = ?
Your inequality is .90d <= 3
.90d / .90 <= 3 / .90
<= 3 1/3 or approximately 3 disks.
To find out how many disks Dan can buy with his remaining money, we need to subtract the amount he has already spent from the total amount he had initially.
Dan had $20.00, and he has already spent $17.00, so we subtract $17.00 from $20.00: $20.00 - $17.00 = $3.00
Now we know that Dan has $3.00 remaining.
To find out how many disks he can buy with his remaining money, we can divide the remaining amount by the cost of each disk:
$3.00 ÷ $0.90 = 3.33 (rounded to the nearest whole number)
Therefore, Dan can buy 3 disks with his remaining money.
