This is how you solve this problem:
.10d + .05n = 5.25
(plug in the number of dimes we have)
(21 x .1) + .05n = 5.25
(multiply number of dimes x value of the dime)
2.10 + .05n = 5.25
(subtract 2.10 from both sides)
.05n = 3.15
(divide both sides by .05 to get the number of nickels)
n = 63 nickels
Hope this helps!

Answer:
nonlinear
Step-by-step explanation:
If the function is linear, evenly-spaced x-values will correspond to evenly-spaced y-values.
Here, the x-values all differ by 1. The y-values differ by 2 and 6, so the function is nonlinear.
She spent 17 hours tutoring
$210 = 7 hours
$20 x 10 hours = $200
$210 + $200 = $410
7 Hours + 10 Hours = 17 Hours
