Ashop sells pineapple smoothies for $2.75 and mango smoothies $3.25. on saturday, a total of 60 cups were used to serve smoothies, and the register showed that a total of $172.50 was collected from smoothie sales. let x represent the number of pineapple smoothies and y represent the number of mango smoothies. which system of equations represents the situation?

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!

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the first one, all those points on the line just make a strait line.
