Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution. Which equation can you use to determine how many gallons of the 35% acid solution Eli should add?
a. (0.10)(0.5) + 0.35g = 0.15 (g + 0.5)
b. (0.10)(0.5) + 0.35g = 0.15 (g + 0.5) + 0.15
c. (g + 0.5) + 0.15 = 0.15(g + 0.5)
d. (0.10)(0.5)(0.35g) = 0.15(g + 0.5)

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
