Jacob purchased pounds of grapes and pounds of strawberries from a farmer's market. the cost of each pound of grapes is $2.64 and the cost of each pound of strawberries is $3.09. if the store offered a discount of 10% on the final bill, what was the amount jacob paid to buy the fruits? ignore sales tax.

Amount of bill after discount will be 45.157

Step-by-step explanation:

We have given that Jacob purchased pounds of grapes and pounds of strawberries

The cost of pound grapes is $2.64 per pound

And the cost of strawberries is $3.09 per pound

So total cost of grapes and strawberries = $2.64+$3.09 = $5.73

It is given that there is discount of 10% on the total bill

So discount

So the amount of bill after discount = $5.73 - $0.573=$5.157

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
