Answer:
10 tacos costs $15.00
Step-by-step explanation:
I like to use ratio's to solve this type of problem. I will put cost over number of tacos.
$6.00 x dollars
-------- = --------------
4 tacos 10 tacos
Using cross products
6 * 10 = 4 * x
60 = 4x
Divide each side by 4
60/4 = 4x/4
15 =x
B) $15.00
well if 4 taco = $6 just divid to see how mutch one taco is
6.00 divided by 4 = $1.50
now just times 1.50 by 10 to get $15
hope this helped
