Onur is participating in a walkathon fundraiser. Two donors promised to donate money based on the total distance he walks. The money, A, in dollars, that he receives from the first donor given that he walks d kilometers is given by the formula A(d)=10d. The money, B, in dollars, that he receives from the second donor given that he walks d kilometers is given by the formula B(d)=2d+d^2. Let T be the total money that Onur raises from those donors by walking d kilometers in the walkathon.

Write a formula for T(d), in terms of A(d) and B(d).
T(d)= ?

Write a formula for T(d), terms of d.
T(d)=?

1. T(d) = A(d) + B(d)

2. T(d) = 12d + d²

Step-by-step explanation:

From the question given above, the following data were obtained:

A(d) = 10d

B(d) = 2d + d²

1. Determination of the formula of T(d) in terms of A(d) and B(d).

T(d) is the total money obtained. Thus,

T(d) = A(d) + B(d)

2. Determination of the formula of T(d) in terms of d.

A(d) = 10d

B(d) = 2d + d²

T(d) =?

T(d) = A(d) + B(d)

T(d) = 10d + 2d + d²

T(d) = 12d + d²

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
