Answer:
C. 1.4x + 1.8y = 79.8
x + y = 53
Step-by-step explanation:
The problem statement gives rise to two equations, one for the amount of money made, and one for the number of items sold. If x and y represent the numbers of items, and if 53 items were sold, then one of the equations will be ...
x + y = 53
This is sufficient to let you choose the correct answer.
___
Since "x" items were sold for $1.40 and "y" items were sold for $1.80, the sales revenue will be the sum of products of price and quantity:
1.40x +1.80y = 79.80
This confirms the choice of answer.

Answer: $2992.26</h3>
===================================================
Explanation:
If you're given a 15% discount, then you still have to pay the remaining 85% (because 100% - 15% = 85%)
Rewrite 85% into 0.85
The multiplier for "15% discount" is 0.85
Similarly, the multiplier for a 6% discount is 0.94; note how 100% - 6% = 94% = 0.94
When we have multiple discounts chained together like this we find the product of the multipliers. So we multiply the 0.85 and 0.94 to get
0.85*0.94 = 0.799
After chaining together the two discounts, you will have to pay 79.9% of the original value. This means the overall discount is 20.1%
Take the result of 0.799 and multiply that with the marketed price of $3745 to get the final answer
0.799*3745 = 2,992.255 which rounds to 2,992.26
Rate = distance / time
Rate = 21 miles / 3 hours
Rate = 7 miles / hour
The answer is choice A. Hope this helps.
