Tyler went to the supermarket to buy food for a food pantry. He has $36, and can carry up to 20 pounds of food in his backpack. Pasta costs $1 for a 1-pound package. Pasta sauce costs $3 for a 1.5 pound jar. Let x = the number of packages of pasta and y = the number of jars of pasta sauce. Select all that apply. Choose the inequalities needed to describe the amount of pasta and pasta sauce that Tyler can buy

Respuesta :

For the answer to the question above asking to choose the inequalities needed to describe the amount of pasta and pasta sauce that Tyler can buy
{x + 3y <=36 
{x + 1.5y <=20 
{x = y 
y+3y<=36 
4y<=36 
y<=9 
y+1.5y<=20 
2.5y<=20 
y<=8 
min(8,9) = 8 
x = 8, y = 8
