harina [27]

Answer:

If gabe has a gift card for $50 then <u>it will cover the cost of jeans. </u>

Step-by-step explanation:

Given:

Gabe is buying a pair of jeans at a local store that are priced at $45.

He knows that the country he lives in has an 8% tax added onto the list price.

Now, if gabe has a gift card for $50 to get will it cover the cost of jeans.

Price of a pair of jeans = $45.

Tax = 8%.

Now, getting the amount of jeans including tax:

$45 + 8% of $45.

= 45+\frac{8}{100} \times 45

=45+0.08\times 45

=45+3.6

=48.6

Thus, the amount of jeans including tax = $48.60.

As, given Gabe has gift card of $50.

Now, subtracting the amount of jeans from amount of gift card:

50-48.60=1.40

So, $1.40 is still remaining.

Therefore, if gabe has a gift card for $50 then it will cover the cost of jeans.

(1/4 cannot be reduced)
1/4 = 1/4

(divided by 2 for both numerator and denominator)
2/8 = 1/4

(divide by 3 for both numerator and denominator)
3/12 = 1/4

------------------------------------------------------------------------------------
Find combined fraction of the mural that has been painted.
------------------------------------------------------------------------------------
1/4 + 1/4 + 1/4 = 3/4
