We have two products: a two-slice toaster and a four-slice toaster.
Lets call T the number of two-slice toasters produced and F the number of four-slice toasters produced.
If we have 300 hours per week of labor, the sum of the labor required for T and F has to be lower or equal to that value.
The labor hours that take to make the two-slice toasters can be written as 6*T, as it is the product of the hours per unit (6 hours/unit) by the number of units (T units).
The same can be done for F, where the labor required can be expressed as 10*T.
If we add these terms, and make them be less or equal than 300, we get:

The production capacity is 40 units, so the sum of T and F has to be less or equal than 40.
We can express this as:

Answer:
The system of inequalities for this problem becomes:

6T+10F<=300
T+F<=40
Answer:
The total charge for these tickets when paying by credit card is £ 90.64.
Step-by-step explanation:
Since Billy wants to buy 4 adult tickets at £ 15 each and 2 child tickets at £ 10 each for a show, and a 10% booking fee is added to the ticket price, and 3% is then added for paying by credit card, for work out the total charge for these tickets when paying by credit card the following calculation must be performed:
((4 x 15 + 2 x 10) x 1.10) x 1.03 = X
((60 + 20) x 1.10) x 1.03 = X
(80 x 1.10) x 1.03 = X
88 x 1.03 = X
90.64 = X
Thus, the total charge for these tickets when paying by credit card is £ 90.64.
Your answer is 0.6
Glad I could help, buddy :)
Please mark me as BRAINLIEST and don’t forget to say “Thanks” lol
This is not an arithmetic sequence.
It does not go up or down by the same amount each time.
It is a geometric sequence
it is multiplied by 5 each time
