Timothy has hired Cynthia and Dominic to cover the roof with shingles. Dominic can install 180 shingles in the same time it takes Cynthia to install 150 shingles, which can be shown using the following relationship where d and c are the respective rates for Dominic and Cynthia: 180 150 d C. Also, Dominic can install 10 shingles more per hour than Cynthia. How many shingles can Cynthia install per hour?

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
