7 and -4
Coefficients are the numbers before a variable, meaning that 7 and -4 (be careful of that subtraction sign) are the coefficients. Additionally if you were asked what the leading coefficient was the answer would be 7 because it has the greatest exponent attached to it (2).

<u><em>Answer:</em></u>
<u><em>$55.93 or rounded up is $56</em></u>
<u><em>Division</em></u>
<u><em>First, we would divide 15.98 by 2 to see how many dollars would a bag cost.</em></u>
<u><em>15.98 divided by 2 = $7.99</em></u>
<u><em>Multiplication</em></u>
<u><em>Then, we would multiply by 7 to see how may dollars would it cost for 7 kg bag</em></u>
<u><em>7.99 times 7 = 55.93</em></u>
<u><em>Round-up</em></u>
<u><em>If we round it up, we get $56.</em></u>
