Lila bought a green poster that measured 36 inches by 24 inches and a red poster that measured 12 inches by 18 inches. if the posters cost $0.05 per square inch, how much did she spend

Total amount she spent on the posters = $43.2  +  $10.8  = $54

Step-by-step explanation:

Lila bought a green poster that measured 36 inches by 24 inches and a red poster that measured 12 inches by 18 inches. The posters cost per square inch is $0.05 .

To know how much she spend on the posters one have to convert the measured values of the posters to square inches(area).

Green poster  

area of rectangle = Lb

area of rectangle = 36 × 24

area of rectangle = 864 square inch

since 1 square inch = $0.05

864 square inch = ?

cross multiply

864 × 0.05 = $43.2

Red posters

area of rectangle = Lb

area of rectangle = 12 × 18

area of rectangle = 216  square inches

since 1 square inch = $0.05

864 square inch = ?

cross multiply

216 × 0.05 = $10.8

Total amount she spent on the posters = $43.2  +  $10.8  = $54

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
