Answer:
30 dollars
Step-by-step explanation:
packages-$12.36 x 2=24.72
broccoli-$1.98/2=.99
milk-$3.49
$24.72+.99=25.71
$25.71+$3.49=29.20
$29.20+.80=30.00
she payed with $30.00
So right now you see that you have x and y intercept right? Then plug those intercepts in equation that you have and solve for z. Which means z=5(1)(1) will be 5, 5(4)(1) will be 20, and 5(1)(2) will be 10. So, overall you have 5, 20, 10.
The gcf of both 6 and 48 is 6. So, in simplest form, the ration would be: 1:6 or 1 hour:6 minutes :)
