Answer:
see explanation
Step-by-step explanation:
Using cross- products, that is
= 
then ad = bc
Given the ratios
and 
Then equating and using cross- products
If both sides equate then the ratios are equivalent
= , then
4 × 21 = 6 × 14 ⇒ 84 = 84
Both sides are equal thus the ratios are equivalent

A = amount
.01a + .05a + .1a = 1.28
Combine like terms.
.16a = 1.28
Divide both sides by .16.
a = 8
8 * 3 = 24

Answer:
y= 1.5x + 2.5
Step-by-step explanation:
So slope intercept form is y= mx + b.
y is the number of minutes, so that will be on the left of the equal sign, not part of the math side of the actual equation, because it's the answer.
1.5x is the mx part because it's 1.5 minutes for each extra patty. So that would explain the x attached to it. so for each extra patty you add, that's what x would be.
The + 2.5 at the end, is just the time for the initial patty.
Hope this helps and is easy to understand! :)
