Rita goes to the mall. If b is the number of items she bought, the expression 14.28b+ 24 gives the amount she spent in dollars at one store. Then she spent 27 dollars at
another store. Find the expression which represents the amount Rita spent at the mall. Then she spent 27 dollars at another store
estimate how much Rita spent if she bought 2 items.​

Ok, so to clarify, she went to 3 stores, is that right? I’ll do this as if the answer is yes. I’ll fix it in comments if your answer is no.

(14.28b + 24) + (27)
14.28b + 51 = amount spent after 2 stores

Then the third store:
14.28b + 78

If b = 2,

14.28(2) + 78 = 28.56 + 78 = $106.56

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
