Asked by Julius Roces

sally saved x dimes the first week, 10x + 2 dimes the second week, and 3x - 1 dimes the third week. If she saved $7.10 in all, find the amount she saved each week.
Answered by R_scott
x + (10 x + 2) + (3 x - 1) = 71

solve for x ... the number of total dimes

substitute back to find the weekly amounts
