Let p = the number of pennies
let q = the number of quarters
p + q = 23
0.01p + 0.25q = 3.11
4+2 = 6 a a a a + a a = a a a a a a
2+4 = 6 a a + a a a a= a a a a a a
Tommy is correct They are both equal to 6
Plug in x = 7
<span>y= 330 - 25(x)
</span><span>y= 330 - 25(7)
</span><span>y= 330 - 175
y = 155</span>
They have the same denominator so add the numerators. It equals 3/7.
