This year, students in the 9th grade are collecting dimes and quarters for a school fundraiser. They are trying to collect more money than the students who were in the 9th grade last year. The students in 9th grade last year collected$143.88. Using to represent the number of dimes collected and to represent the number of quarters, which statement best represents this situation?

D

Step-by-step explanation:

This year's 9th graders wanted to make MORE than last years 9th graders. this means that we will use the greater than sign, not the greater than or equal to sign. Now we can cross out the first two. we are now left with the bottom two equations. quarters are 25 cents and dimes are 10 cents, knowing that q = quarters and d = dimes we know where to put the variables. 0.25q stands for 25 cents times however many quarters, this is the same with 0.1d. This is why the answer is D and not C. It wouldn't make sense for it to be .1q because quarters do not equal 10 cents. hope this makes sense.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
