Answer:
x = 45
y = 15
Step-by-step explanation:
Given that:
x = pineapple smoothies
y = mango smoothies
According to given conditions:
x + y = 60.................... eq1
$2.75 x + $3.25y = $172.50 ............ eq2
By taking eq1
x + y = 60
x = 60 - y
Putting value of x in eq2
$2.75 (60 - y) + $3.25y = $172.50
By simplifying
$165 - $2.75y + $3.25y = $172.50
Adding like terms:
$0.5y = $172.50 - $165
$0.5y = $7.5
Dividing both sides by $0.5
y =7.5/0.5
y =15
Putting value of y in eq 1
x + 15 = 60
x = 60 -15
x = 45
So there are 45 pineapple smoothies and 15 mango smoothies.
i hope it will help you!
Answer:
y= -x+60
2.75x+3.25y= 172.50
Step-by-step explanation:
The sum of the variables gives the total, 60, so x+y=60, which is equivalent to y=60−x. The cost of the pineapple smoothie, 2.75, times x plus the cost of the mango smoothie, 3.25, times y gives the total amount, $172.50. So the second equation is 2.75x+3.25y=172.50.
