To answer this question, we need to first know what f(x) means. For example, if f(10), then you plug in 10 for x, 7(10)+2 = 72.
Do the same thing but with f(7).
f(7) = 7(7)+2
f(7) = 49+2
f(7) = 51
Hope this helps.

Alec and Kiara went to Freddy's Yogurt Shop for frozen yogurt. Alec got 8.6 ounces of strawberry frozen yogurt, and Kiara got 8.
LiRa [457]

Answer:

$8.40

Step-by-step explanation:

8.6 plus 8.2 is 16.8 so they had a total of 16.8 ounces.  $0.50 per ounce so you need to multiply 16.8 by 0.50 which is 8.40.  you can also do 8.6(0.5) plus 8.2(0.5)=  4.3 plus 4.1 = 8.4
