Shannon and Piper are on the school golf team. Shannon buys 10 cheap golf balls and 7 expensive ones for $31.75. Piper buys 8 cheap and 5 expensive balls for $23.75. Write and solve a system of equations (using a 4-step solution) to find the prices of each of the two kinds of golf balls.

sorry i need points

Step-by-step explanation:

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

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.
