Answer:

13 glue sticks cost $25.22.
Step-by-step explanation:
4 blue sticks cost $7.76, this means that one glue stick costs
$7.76/4 = $1.94.
Let
be the cost of the glue sticks, and
be the number of glue sticks; then

We can use this equation to find the cost of 13 glue sticks; we just put
into our equation and it gives:

So 13 glue sticks cost $25.22.
<span>We are given with a 1150$ budget and an expense of $84 and $99 for each watch.
Let's say the number of watches = x
1150 = 84 + (99x)
1150 - 84 = 99x
(1150 - 84)/99 = x
Rounding down the answer, x or the number of watches is equal to 10 watches.</span>
