Final answer:
The equation $2.00/pound × x pounds of peaches = $15 determines that 7.5 pounds of peaches were bought for $15. No equation for y can be deduced from the given information as it pertains to apples, which are not discussed in the scenario.
Step-by-step explanation:
The question asks to express y in terms of x, given the price of peaches. The provided equation $2.00/pound × x pounds of peaches = $15 represents the total amount spent on peaches. To find x, you would divide the total amount spent by the price per pound.
x = $15 / $2.00/pound
Therefore, x equals 7.5, meaning 7.5 pounds of peaches were purchased for $15.
The question does not provide enough information to formulate an equation for y, as y represents the number of pounds of apples and we have no information about apples in this scenario.
