Answer:
69.75 miles
Step-by-step explanation:
Akim runs 1.75 miles on his first day of training.
He increases his distance run by 0.25 miles the day after that i.e.
He runs 1.75+0.25 miles
On third day again he increases his distance by 0.25 miles i.e.
He runs 1.75+0.25+0.25 miles
i.e. on nth day he runs 1.75+0.25(n-1)
Total number of miles Akim runs over the course of 18 days is:
=69.75 miles

For the first part:
Every shirt she grabs, will cost her dollars, so if she grabs 3 shirts, then the cost of the shirts is:
With the same rationale, if she grabs 2 pairs of jeans, the cost of the jeans is:
So, her total is:
If you subtract 3 from the total, then the expression is:
For the second part:
If she's paying 3 less for each shirt, then the cost of 3 shirts will become:
In the same fashion, for the two jeans:
So the expression for the total cost is:
For number three:
The amounts are different because the cost of the total purchase is different than the cost of each element that makes up the total purchase.
For number four:
If you're the owner, you want to give the smallest amount of discount (the one in part 1/a).
So you could clarify by saying there's 3 dollars of the TOTAL purchase's cost.
