Answer:
dogs = 2
cats = 80
Step-by-step explanation:
Here I will assume that cats and dogs are proportional
c = y d, if you substitue, you get
10 = y 4, which rearranged, becomes
y = 10/4 = 2.5
now that we know y, we can work out x and y, the missing dogs and cats
4 = 2.5 d
here, dogs = 2
c = 2.5 * 32
2.5 * 32 = 80
here, cats = 80

Answer:
A. 25n + 15x
B. $358.75
Step-by-step explanation:
Jocelyn earns
Grocery store= $x per hour
Babysitting= $n per hour
A. Write an expression that describes her earnings if she babysat for 25 hours and worked at the grocery store for 15 hours.
The expression is:
25n + 15x
B. How much money did she earn if she charged $10 an hour for babysitting and earned $7.25 an hour at the grocery store.
25n + 15x
When n= $10 and x= $7.25
25n + 15x
= 25(10) + 15(7.25)
= 250 + 108.75
= $358.75
Therefore, if Jocelyn earns $10 per hour for babysitting and babysat for 25 hours, and earn $7.5 per hour at the grocery store and works for 15 hours.
Her total earnings will be $358.75
