d.
9 scoops of red sand for every 6 scoops of blue sand

Option D

ANSWER:  

9 scoops of red sand for every 6 scoops of blue sand maintains the ratio Ross wants.

SOLUTION:

Given, Ross is making colored sand for an art project.  

He mixes 3 scoops of red sand for every 2 scoops of blue sand.

First, let us calculate the ratio of given information.

ratio of red sand to blue sand = 3 : 2

Now, let us check the options.

A. 12 scoops of red sand for every 9 scoops of blue sand

Here, ratio of red sand to blue sand = 12 : 9 = 4 : 3

This ratio does not matches with our ratio. So this is not correct option.

B. 10 scoops of red sand for every 8 scoops of blue sand  

Here, ratio of red sand to blue sand = 10 : 8 = 5 : 4

This ratio does not matches with our ratio. So this is not correct option

C. 8 scoops of red sand for every 12 scoops of blue sand  

Here, ratio of red sand to blue sand = 8 : 12 = 2 : 3

This ratio does not matches with our ratio. So this is not correct option

D. 9 scoops of red sand for every 6 scoops of blue sand

Here, ratio of red sand to blue sand = 9 : 6 = 3 : 2

This ratio matches with our ratio. So this is correct option.

Hence, correct option is D.

d. is the correct answer

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
