The school store sells pencils for $0.30 each, hats for $14.50 each, and binders for $3.20 each. Elena would like to buy 3 pencils, a hat, and 2 binders. She estimated that the cost will be less than $20.

1. Do you agree with her estimate? Explain your reasoning.

2. Estimate the number of pencils could she buy with $5. Explain or show your reasoning

Answers

1. No I do not agree with her estimate, because after adding up all of the cost of the things she wants to purchase, the cost will be over 20 dollars.

2. With 5 dollars she could buy 16 pencils. .30x16=4.80, so she could buy 16 pencils

Area=6

Step-by-step explanation:

the pigpen is not a square so it could be a rectangle or any other shape with four sides. since the pigpen has four equal angles and it's not a square it's a rectangle. one side of the pigpen is three feet long--REMEMBER THAT!!! one foot short of 7 feet is six feet and that is the distance around the pigpen or the perimeter

Time to solve

because the perimeter is 6 feet and one of the sides is three feetwe divide 6 by 3 and get two which is our widthwe then multiply 2x3 to get 6
Area=6

Answers

The equation would be y+3=(1/4)(x+3)
Gradient of the perpendicular line is the negative reciprocal of the original line.
So the gradient is 1/4
