Answer :
Answer:
[tex]1.80(3.9)=t[/tex]
Step-by-step explanation:
$1.80 is the cost of grapes per pound, so multiplying by the # of pound of grapes being bought will give us the total price. Lets make a general equation for finding the total price of grapes per pound.
the # of pounds = p, and the total cost of grapes = t.
[tex]1.80p = t[/tex]
Caden is buying 3.9 pounds of grapes, so we can multiply that by the cost of 1 pound for grapes to find the cost of 3.9 pounds of grapes. For Caden, p = 3.9, and we are looking for t. Plug in 3.9 to find the expression needed to find the total cost of grapes for Caden,
[tex]1.80(3.9)=t[/tex]
Caden's t = $7.02
