write down the algebric equation for Sandra's budget constraint.

Expert's answer

Equation looks like

2.99x+2.89y=7,000

Where x is the quantity of minutes for digicel,

y is the quantity of minutes for limeare

Or in a more familiar form

Y=(7,000-2.99x)/2.89;

Y=2,42215-1.03x

Answer.

2.99x+2.89y=7,000

2.99x+2.89y=7,000

Where x is the quantity of minutes for digicel,

y is the quantity of minutes for limeare

Or in a more familiar form

Y=(7,000-2.99x)/2.89;

Y=2,42215-1.03x

Answer.

2.99x+2.89y=7,000
