A reasonable prediction of the distance d in feet, that a car travels after the driver has applied the brakes can be found by using the formula d = 0.055r 2 , where r is the speed of the car in miles per hour. If Mario is driving at 60 miles per hour and applies the brakes, then according to the formula, how many feet will Mario’s car travel before it stops?

Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation Subtract y from 5 as 5 – y. b. Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. For example, describe the expression 2 (8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms. c. Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas V = s3 and A = 6 s2 to find the volume and surface area of a cube with sides of length s = 1/2. The Music Palace is having a sale
