Aaron has $150 at the start of the week. By the end of the week, he has 30% more money. How much total money does he have at the end of the week? Show work, using any method.

$195

Step-by-step explanation:

To solve a percent problem, you can use the equation:     part            %

                                                                                                   =    

                                                                                               whole         100

You want to find 30 percent, so the % would be 30. You also want to find 30% of 150, so the whole would be 150 and the part would be x. Cross multiply to get     100x = 4500. Then, divide 4,500 by 100. The equation should look like this:  x = 45. Add 45 to $150 to get $195. So Aaron has $195 at the end of the week.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
