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