Jim is going to buy donuts for his family. Each donut costs $1.45. If the number of donuts Jim buys is represented using the letter d, which expression represents the total cost?
a
1.45/d
b
1.45 - d
c
1.45 + d
d
1.45d
d) 1.45d
This is correct.
The correct expression that represents the total cost is d multiplied by $1.45.
So the correct answer is d multiplied by 1.45, which is represented by expression d * 1.45.
Hence, the correct choice is option d: 1.45d.
The total cost of the donuts can be calculated by multiplying the cost per donut ($1.45) by the number of donuts Jim buys (d). Therefore, the expression that represents the total cost is 1.45d.
So the answer is option d.
