Jenny has six basketball teams, each team needs new shoes for an upcoming tournament, and she spent 630 dollars on all the shoes thus far. each pair of shoes cost 6 more than last year's pairs of shoes. how much did last year's shoes cost?

SInce there are six teams and each pair of shoes for each individual player is $630, set up this equation:

630 (total thus far) = 6x (six times the cost of last year)

630/6 = x

This means that last year's cost was $105.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

so, converting firstly the mixed fractions to improper fractions and then "adding".
