Answer:
The ratio of x:y is 1/2
Step-by-step explanation:
Let
x----> the number of Kg of brand A
y ---> the number of Kg of brand B
we know that
400x+280y=320(x+y)
400x+280y=320x+320y
400x-320x=320y-280y
80x=40y
x/y=40/80
x/y=1/2
Answer:
$64
Step-by-step explanation:
The cost of food ($60) leads to a 15% tip. The tip amount is calculated as follows: 0.15($60) = $4.
Adding the food cost and the tip amounts, we get $64, the total cost of the meal.
A faster approach would be to combine 1($60) + 0.15($60) into an expression of a single term: (1 + 0.15)($60 = 1.15($60) = $64.
