Answer:
$4.80
Step-by-step explanation:
First, apply the coupon to the original price
20% of 14.99 = 2.998
or
0.20 x 14.99 = 2.998
Then, find the sales tax of the new price
%6 of 2.998 = 1.7988
or
0.60 x 2.998 = 1.7988
Finally, add the sales tax to the new price
2.998 + 1.7988 = 4.7968
Round 4.7968 to the nearest tenth to get 4.80

Test contains 10 three-point questions and 14 five-point questions.
For this case, the first thing we must do is define variables.
We have then:
f: number of points that fabio scored.
c: number of points that Carlos scored.
We now write the equation that models the problem:
Then, for f = 31 we have:
From here, we clear the number of points:
Answer:
The equation to find the number of carlos points is:
