Sue drove her car 253 miles in january, 277 miles in february, and 280 miles in march. if her average mileage for the four months from january to april is to be at least 284 miles, how many miles must she drive in april

Respuesta :

Americ
x= miles driven in April


(253 + 277 + 280 + x)/4= 284
add in parentheses

(810 + x)/4= 284
multiply both sides by 4

810 + x= 1136
subtract 810 from both sides

x= 326 miles


ANSWER: She must drive 326 miles in April to average at least 284 miles January through April.

Hope this helps! :)
