Answer:

$560

Step-by-step explanation:

10% of $400 is $40. 40% of $400 is 10%x4. 40% of $400 is $160. Since her allowance increased by $160, it is now $560 per week.

What is the surface area for this design?
Umnica [9.8K]

Answer:

Surface Area = 157 in^2

Step-by-step explanation:

Surface area is the area of each side added together.

Front = Trapezoid =  <u>b1 + b2</u> * h          <u> 5 + 9 </u>  *  5   = 27.5              

                                        2                        2                              

Back = Trapezoid =  <u>b1 + b2</u> * h           <u> 5 + 9 </u>  *  5   = 27.5               27.5

                                        2                        2                                        27.5

Right = Rectangle = l * w                      6.4 * 5 =  32                           32

Left = Rectangle = l * w                           5 * 5 =  25                           25

Bottom = Rectangle = l * w                     9 * 5 =  45                           45

Top = Rectangle = l * w                          5 * 5 =  25                          <u> 25     </u>

                                                                                                             157 in^2
