Alocal salesman receives a base salary of $975 monthly. he also receives a commission of 6% on all sales over $1100. how much would he have to sell in a month if he needed to have a monthly income of $2100? he would need to sell $ to reach his needed monthly income needs. (round answer to the nearest penny. do not use commas! )

salary + comission = income

975 + .06 (sales-1100) = income

975 + .06 (sales -1100) = 2100

subtract 975 from each side

.06 (sales -1100) =1125

divide by .06

sales - 1100 = 18750

add 1100 to each side

sales = $19,850.00

they will manufacture 8496 cars

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
