I'm trying to do this problem, but i have no idea how to even start it:

shirts. com advertises a limited time sale, offering 1 turtleneck sweater for $15 and 2 turtleneck sweaters for $25. a total of 1250 turtlenecks are sold and $16,750 is taken in. how many customers ordered 2?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

tube or goog would be a great resource to with that question
