Robert bought 3 baseball caps for the same amount and 1 baseball jersey that cost $45. Without tax, the total cost of the items is $90. What is the cost of each baseball cap?

Unitary cost= $15

Step-by-step explanation:

First, we need to calculate the total cost of the baseball caps:

Total cost baseball caps= 90 - 45

Total cost baseball caps= $45

Now, the unitary cost of each baseball caps:

Unitary cost= total cost / number of units

Unitary cost= 45/3

Unitary cost= $15

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
