The base (with a *positive* exponent) is 7/6, a number larger than 1. Because multiplying by a number larger than 1 makes the quantity increase, this is a growth (not decay) model.
The growth factor is 7/6.
The percentage increase in each time period is (7/6 -1)*100% ≈ 16.67%.
Earnings: $2900
Expenditure on food: $290
Percentage expenditure on food = Expenditure on food / Earnings times 100
= $290/$2900 * 100 = 10%
There are 4 bees and 12 ladybugs. So the ratio is
4 : 12
Reduce to lowest term, we get :
1 : 3
4w+x-4
Because when multiplying by a negative with a negative you will get a positive and multiplying a negative with a positive will get you a negative
