Question

Abby wants to buy some fruit. She has $10.00 to spend. Apples (x) cost $0.50 a pound and bananas (y) cost $1.50 a pound. Which graph shows all of the ways she can spend up to $10.00 on apples and bananas?

Answer 1

We are given with a total of $ 10.00 to spend for apples and bananas. The number of pounds of apples bought is represented by x and that of bananas is
represented by y. Each apple costs $0.50 per pound
while banana costs $1.50 per pound. The expression
s represented by 0.50 x + 1.50 y = 10 or y = -0.33
x + 6.67. This function is a linear function going
downwards with a slope of -0.33 and a y-intercept
of 6.67.
