The exchange rate at the time of James' holiday
was $1.45 to £1
Work out, in £, the total cost of his holiday.

£2,450

Step-by-step explanation:

What we want to do here is calculate the total amount spent on his birthday in £

We already have some costs in pounds, it is the costs not in pounds we are converting.

Flights already in pounds, no conversion

Hotel $105 per night at 14 days

Total here is 14 * 105 = $1470

Wifi cost at $4 per day for 13 days

Total here is 13 * 4 = $52

Total amount spent in dollars alone is $1470 + $52 = $1522

We try and covert this to pounds

$1.45 = £1

$1522 = £x

We simply cross multiply at this point

x = 1522/1.45 = 1049.65 which is approximately £1050

Total amount spent in £ is thus 1050 + 1400 = £2,450

£2449.65

Step-by-step explanation:

105 × 14 = $1470

1470 ÷ 1.45 = £1013.79

13 × 4 = $52  

52 ÷ 1.45 = £35.86

£1013.79 +  £35.86 = £1049.65

£1049.65 + 1400.00 = £2449.65

The total cost was £2449.65

- 70

this is the answer for you hope it

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
