Adult spent 10+ 1.50 x 7= $20.50
Child spent 6+ 1 x 7= $13
So in all the Adult spent $7.50 more than the child did.
To find the x intercept, sub in 0 for y and solve for x...
-2x + 5y = -20
-2x + 5(0) = -20
-2x = -20
x = -20/-2
x = 10....so the x int is (10,0)
For #7,
2 3/8% < 2 1/2% < 2 2/3% < 2 4/5%
For #8,
<em>The answer is $80, here's how:</em>
$32 = 40%
100% = ?
(I don't really know a way better than this, sorry, even tho I am sure of the answer)
40% ÷ 2 = 20%
32 ÷ 2 = 16 <em>
20% = 16
</em>100% = 40% + 40% + 20%
<em>100% = 32 + 32 + 16
</em>100% = $80
<em>
</em>
I have no idea but I’ll go with 60% cause there’s no picture
