The local supermarket is having a holiday special on lollipops. The rainbow lollipops, x, cost $2 and the blue lollipops, y, cost $1. At the end of the day, the supermarket sold a total of 185 lollipops with a total profit of $320. Given the system of equations below, find the solution and what it means in context to the situation. 2x+y=320 y=-x+185 *

135 rainbow lollipops were sold ($270) and 50 blue lollipops were sold ($50).

Step-b-step explanation:

Cost of rainbow lollipops: 2

Cost of blue lollipops: 1

2x + y = 320

x + y = 185, y = 185 - x

Solve with substitution:

2x + (185 - x) = 320

x = 135

y = 50

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
