Answer:
4 maybe, sry if im wrong
Step-by-step explanation:
Since $45 is 60% of the total cost, you can make an equation or a proportion to solve it....
45 = .6x for example, now divide by .6 and you'll get 75.
So 45 is 60% of 75 and the total cost then is $75

Answer:
$9.98
Step-by-step explanation:
The first step is to calculate the total fabric that Calista has
= 2 1/2 + 1 3/4
= 5/2 + 7/4
= 17/4
The next step is to calculate the fabric that she needs
= 17/4-3
= 5/4
If each yard of fabric costs $7.98 then the amount needed can be calculated as follows
= 7.98 × 5/4
= 7.98 × 1.25
= 9.975
= $9.98
Hence Kalista needs $9.98
The total change in temperature was 28 degrees
