The baker pays $0.80 per pound for sugar and $1.25 per pound for butter. write an expression that shows how much the baker will spend if he buys 6 pounds of butter and 20 pounds of sugar.

$0.80x + $1.25y = z

Step-by-step explanation:

the total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.

2

step-by-step explanation:

1+1=2

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
