lindsey made 400 tarts. she sold 3/5 of them in morning and 1/4 of the remainder in the afternoon. how many tarts did she sell in the afternoon?

40 tarts

Step-by-step explanation:

Lindsey had 400 tarts to start with, then she sold off 3/5 of them. Hence find the number of tarts left (2/5 of the original amount). Then she sold 1/4 of the remaining tarts. Therefore, find 1/4 or 2/5 of 400. The equation would be;

Now one just has to solve the equation;

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.
