Two students went to the school store. Each had a $20 bill. Jacob bought 3 of an item and received change. Quinn bought 7 of the same item and also received change. The total amount of change between them was $25. Write and solve an equation to find which item the students bought. (PLS HELP MEH! PLS I HATE THIS STUFF BUT I LOVE IT MAH TEACHERS STOOPID!)

X= $1.5

Step-by-step explanation:

y=mx +b

Y= total amount they had,  M= the amount they bought,  X= how much the item cost, B= the amount they of change they had left

40= 10x + 25

Subtract 25 from both sides

40-25= 15

15= 10x

divide 10 from both sides

15/10= 1.5

x= 1.5

step-by-step explanation:

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.
