To predict the number of balloons sold during week 8, we can plug x = 8 into the equation y = -1.4x + 30.5:
y = -1.4(8) + 30.5
y = -11.2 + 30.5
y = 19.3
Rounding to the nearest whole number, the store is predicted to sell 19 balloons during week 8.
y = -1.4(8) + 30.5
y = -11.2 + 30.5
y = 19.3
Rounding to the nearest whole number, the store is predicted to sell 19 balloons during week 8.
